Strength Of Materials A Practical Approach Vol I

The theoretcal as well as practical aspects of the strength of materials are presented in this book in a systematic way to enable students to understand the basic principles and prepare themselves for the tasks of designing large structures subsequently. The system of units, notation and conventions are explained clearly, along with a brief historical review of the developments in structural mechanics.

The book includes the elementary topics of the course on Strength of Materials for undergraduate programmes in engineering and technology. It is developed in the SI units adopting international notation and conventions. Several typical example problems are presented systemaically, and exercise problems are included to help candidates improve their concepts.

The fourth edition ofApplied Statics and Strength of Materialspresents an elementary, analytical, and practical approach to the principles and physical concepts of statics and strength of materials. It is written at an appropriate mathematics level for engineering technology students, using algebra, trigonometry, and analytic geometry. A knowledge of calculus is not required for understanding the text or for working the problems. The book is intended primarily for use in two-year or four-year technology programs in engineering, construction, or architecture. Much of the material has been classroom tested in our Accreditation Board for Engineering and Technology (ABET) accredited engineering technology programs as well as in our American Council for Construction Education (ACCE) accredited construction technology program. The text can also serve as a concise reference guide for undergraduates in a first Engineering Mechanics (Statics) and/or Strength of Materials course in engineering programs. Although written primarily for the technology student, it could also serve as a valuable guide for practicing technologists and technicians as well as for those preparing for state licensing exams for professional registration in engineering, architecture, or construction. The emphasis of the book is on the mastery of basic principles, since it is this mastery that leads to successful solutions of real-life problems. This emphasis is achieved through abundant worked-out examples, a logical and methodical presentation, and a topical selection geared to student needs. The problem-solving method that we emphasize is a consistent, comprehensive, step-by-step approach. The principles and applications (both examples and problems) presented are applicable to many fields of engineering technology, among them civil, mechanical, construction, architectural, industrial, and manufacturing. This fourth edition was prepared with the objective of updating the content where necessary and rearranging and revising some of the material to enhance the teaching aspects of the text. While the primary unit system remains the U.S. Customary System, metric (SI) units continue to be used throughout the text, and the examples and problems reflect a mix of the two measurement systems. The homework problem sets have some additions and some deletions, and some other problems were revised. The book includes the following features: Each chapter is written to introduce more complex material gradually. Problems are furnished at the end of each chapter and are grouped and referenced to a specific section. These are then followed by a group of supplemental problems provided for review purposes. Generally, problems are arranged in order of increasing difficulty. A summary at the end of each chapter presents a thumbnail sketch of the important concepts presented in the chapter. Useful tables of properties of areas and conversion factors for U.S. Customary-SI conversion are printed inside the covers for easy access. Most chapters contain computer problems following the section problems. These problems require students to develop computer programs to solve problems pertinent to the topics of the chapter. Any appropriate computer software may be used. The computer problems are another tool with which to reinforce students' understanding of the concepts under consideration. Answers to selected problems are provided at the back of the text. The primary unit system in this book remains the U.S. Customary system. SI, however, is fully integrated in both the text and the problems. This is a time of transition between unit systems. Much of the new construction work in the public sector (particularly in the transportation field) now uses metric (SI) measurement; full conversion to SI in the technology field in the United States is inevitable and will undoubtedly occur eventually. Technicians and technologists must be familiar with both systems. To make the book self contained, design and analysis aids are furnished in an extensive appendix section. Both U.S. Customary and SI data are presented. Calculus-based proofs are introduced in the appendices. The Instructor's Manual includes complete solutions for all the end-of-chapter problems in the text. There is sufficient material in this book for two semesters of work in statics and strength of materials. In addition, by selecting certain chapters, topics, and problems, the instructor can adapt the book to other situations, such as separate courses in statics (or mechanics) and strength of materials. Thanks are extended to many colleagues, associates, and students who with their enthusiastic encouragement, insightful comments, and constructive criticisms have helped with the input for this edition. A special word of thanks goes to James F. Limbrunner, P.E., for his contributions to the text and help with proofreading and problem sets. Also, appreciation is extended to the reviewers for this edition for their help and constructive suggestions: Elliot Colchamiro, New York City Technical College, and Dorey Diab, Stark State College. And last, my thanks to Jane Limbrunner for her support, patience, and understanding during the term of this project. George F. Limbrunner

A Practical Approach to Fracture Mechanics provides a concise overview on the fundamental concepts of fracture mechanics, discussing linear elastic fracture mechanics, fracture toughness, ductile fracture, slow crack propagation, structural integrity, and more. The book outlines analytical and experimental methods for determining the fracture resistance of mechanical and structural components, also demonstrating the use of fracture mechanics in failure analysis, reinforcement of cracked structures, and remaining life estimation. The characteristics of crack propagation induced by fatigue, stress-corrosion, creep, and absorbed hydrogen are also discussed. The book concludes with a chapter on the structural integrity analysis of cracked components alongside a real integrity assessment. This book will be especially useful for students in mechanical, civil, industrial, metallurgical, aeronautical and chemical engineering, and for professional engineers looking for a refresher on core principles. Concisely outlines the underlying fundamentals of fracture mechanics, making physical concepts clear and simple and providing easily-understood applied examples Includes solved problems of the most common calculations, along with step-by-step procedures to perform widely-used methods in fracture mechanics Demonstrates how to determine stress intensity factors and fracture toughness, estimate crack growth rate, calculate failure load, and other methods and techniques

Introduces the basic concepts and their application to solve practical problems. The fundamentals and the assumptions made in the 'Strength of Materials' approach are explained while the basic concepts of mechanics-equilibrium, compatibility and constitutive equations are introduced.

With the advent of a host of new materials ranging from shape memory alloys to biomaterials to multiphase alloys, acquiring the capacity to model inelastic behavior and to choose the right model in a commercial analysis software has become a pressing need for practicing engineers. Even with the traditional materials, there is a continued emphasis on optimizing and extending their full range of capability in the applications. This textbook builds upon the existing knowledge of elasticity and thermodynamics, and allows the reader to gain confidence in extending one's skills in understanding and analyzing problems in inelasticity. By reading this textbook and working through the assigned exercises, the reader will gain a level of comfort and competence in developing and using inelasticity models. Thus, the book serves as a valuable book for practicing engineers and senior-level undergraduate/graduate-level students in the mechanical, civil, aeronautical, metallurgical and other disciplines. The book is written in three parts. Part 1 is primarily focused on lumped parameter models and simple structural elements such as trusses and beams. This is suitable for an advanced undergraduate class with just a strength of materials background. Part II is focused on small deformation multi-dimensional inelasticity and is suitable for a beginning graduate class. Sufficient material is included on how to numerically implement an inelastic model and solve either using a simple stress function type of approach or using commercial software. Case studies are included as examples. There is also an extensive discussion of thermodynamics in the context of small deformations. Part III focuses on more advanced situations such as finite deformation inelasticity, thermodynamical ideas and crystal plasticity. More advanced case studies are included in this part. • This textbook takes a new, task- or scenario-based approach to teaching and learning inelasticity. The book is written in an active learning style that appeals to engineers and students who wish to design or analyze structures and components that are subject to inelasticity. • The book incorporates thermodynamical considerations into the modeling right from an early stage. Extensive discussions are provided throughout the book on the thermodynamical underpinnings of the models. • This textbook is the first to make extensive use of MATLAB to implement many inelasticity models. It includes the use of concepts such as Airy stress functions to solve plane problems for inelastic materials. The MATLAB codes are listed in the appendix for one to modify with their own models and requirements. • Step-by-step procedures for formulations and calculations are provided for the reader to readily adapt to the inelastic problems that he or she attempts to solve. • A large number of problems, exercises and projects for one to teach or learn from are included. These can be assigned as homework, in-class exercises or projects. • The book is written in a modular fashion, which provides adequate flexibility for adaptation in classes that cater to different audiences such as senior-level students, graduate students, research scholars, and practicing engineers.

Now in its second English edition, Mechanics of Materials is the second volume of a three-volume textbook series on Engineering Mechanics. It was written with the intention of presenting to engineering students the basic concepts and principles of mechanics in as simple a form as the subject allows. A second objective of this book is to guide the students in their efforts to solve problems in mechanics in a systematic manner. The simple approach to the theory of mechanics allows for the different educational backgrounds of the students. Another aim of this book is to provide engineering students as well as practising engineers with a basis to help them bridge the gaps between undergraduate studies, advanced courses on mechanics and practical engineering problems. The book contains numerous examples and their solutions. Emphasis is placed upon student participation in solving the problems. The new edition is fully revised and supplemented by additional examples. The contents of the book correspond to the topics normally covered in courses on basic engineering mechanics at universities and colleges. Volume 1 deals with Statics and Volume 3 treats Particle Dynamics and Rigid Body Dynamics. Separate books with exercises and well elaborated solutions are available.
