Non-Destructive Material Characterization Methods provides readers with a trove of theoretical and practical insight into how to implement different non-destructive testing methods for effective material characterization. The book starts with an introduction to the field before moving right into a discussion of a wide range of techniques that can be immediately implemented. Various imaging and microscopy techniques are first covered, with step-by-step insights on characterization using a polarized microscope, an atomic force microscope, computed tomography, ultrasonography, magnetic resonance imaging, infrared tomography, and more. Each chapter includes case studies, applications, and recent developments. From there, elemental assay and mapping techniques are discussed, including Raman spectroscopy, UV spectroscopy, atomic absorption spectroscopy, neutron activation analysis, and various others. The book concludes with sections covering displacement measurement techniques, large-scale facility techniques, and methods involving multiscale analysis and advanced analysis. Provides an overview of a wide-range of NDT material characterization methods, strengths and weaknesses of these methods, when to apply them, and more Includes eddy current sensing and imaging, ultrasonic sensing and imaging, RF and THz imaging, internet and cloud-based methods, among many others Presents case studies, applications and other insights on putting these methods into practice

The Welding Engineer's Guide to Fracture and Fatigue provides an essential introduction to fracture and fatigue and the assessment of these failure modes, through to the level of knowledge that would be expected of a qualified welding engineer. Part one covers the basic principles of weld fracture and fatigue. It begins with a review of the design of engineered structures, provides descriptions of typical welding defects and how these defects behave in structures undergoing static and cyclical loading, and explains the range of failure modes. Part two then explains how to detect and assess defects using fitness for service assessment procedures. Throughout, the book assumes no prior knowledge and explains concepts from first principles.

Additive manufacturing (AM) is a fast-growing sector with the ability to evoke a revolution in manufacturing due to its almost unlimited design freedom and its capability to produce personalised parts locally and with efficient material use. AM companies, however, still face technological challenges such as limited precision due to shrinkage, built-in stresses and limited process stability and robustness. Moreover, often post-processing is needed due to high roughness and remaining porosity. Qualified, trained personnel are also in short supply. In recent years, there have been dramatic improvements in AM design methods, process control, post-processing, material properties and material range. However, if AM is going to gain a significant market share, it must be developed into a true precision manufacturing method. The production of precision parts relies on three principles: Production is robust (i.e. all sensitive parameters can be controlled). Production is predictable (for example, the shrinkage that occurs is acceptable because it can be predicted and compensated in the design). Parts are measurable (as without metrology, accuracy, repeatability and quality assurance cannot be known). AM of metals is inherently a high-energy process with many sensitive and inter-related process parameters, making it susceptible to thermal distortions, defects and process drift. The complete modelling of these processes is beyond current computational power, and novel methods are needed to practicably predict performance and inform design. In addition, metal AM produces highly textured surfaces and complex surface features that stretch the limits of contemporary metrology. With so many factors to consider, there is a significant shortage of background material on how to inject precision into AM processes. Shortage in such material is an important barrier for a wider uptake of advanced manufacturing technologies, and a comprehensive book is thus needed. This book aims to inform the reader how to improve the precision of metal AM processes by tackling the three principles of robustness, predictability and metrology, and by developing computer-aided engineering methods that empower rather than limit AM design.

Thermoplastics and Thermoplastic Composites, Third Edition bridges the technology and business aspects of thermoplastics, providing a guide designed to help engineers working in real-world industrial settings. The author explores the criteria for material selection, provides a detailed guide to each family of thermoplastics, and explains the various processing options for each material type. More than 30 families of thermoplastics are described with information on their advantages and drawbacks, special grades, prices, transformation processes, applications, thermal behavior, technological properties (tenacity, friction, dimensional stability), durability (ageing, creep, fatigue), chemical and fire behavior, electrical properties, and joining possibilities. In this third edition, standards and costs have been updated for all materials, and more information on topics such as bioplastics, 3D printing and recycling have been added. In addition, an entirely new chapter on the concept of ‘Industry 4.0’ has been added, with guidance and suggestions on the incorporation of virtualization, connectivity, and automation into the plastics engineering process to reduce materials and processing failure. Includes detailed case studies that illustrate best practices across a wide range of applications and industry sectors Presents a new chapter on the ‘Industry 4.0’ concept Suggests software solutions to assist with design, decision-making and management, along with other forms of automation
