Topology Based Modeling Of Textile Structures And Their Joint Assemblies

This book presents the textile-, mathematical and mechanical background for the modelling of fiber based structures such as yarns, braided and knitted textiles. The hierarchical scales of these textiles and the structural elements at the different levels are analysed and the methods for their modelling are presented. The author reports about problems, methods and algorithms and possible solutions from his twenty year experience in the modelling and software development of CAD for textiles.

With the growth of applications of textiles in various multidisciplinary domains e.g., clothing, home textiles, and technical applications, there is a need of book covering fundamentals of textiles. This introductory-level textbook is geared toward the introduction of textile engineering. This book is beneficial for all readers who are going to start their career in textiles or related domains or are going to start an engineering degree in textiles.

Design and Manufacture of Structural Composites provides an overview of the main manufacturing challenges encountered when processing fibre-reinforced composite materials. Composites are unique in that the material is created at the same time as the structure, forming a very close link between the constituents, the manufacturing process and the resulting mechanical performance. This book takes an in-depth look at material choices and the intermediate steps required to convert different fibre and matrix combinations into finished products. It provides an insight into recent developments for each of the manufacturing processes covered, addressing design, cost, rate and mechanical performance. Topics covered include an introduction to composite materials, material preforming and conversion, moulding, digital design and sustainability, which addresses waste reduction, disassembly and fibre recovery. This book has been developed primarily as a teaching resource with contributions from leading experts in the field. The content has evolved from courses given by the authors to mechanical engineering and materials science students, at both undergraduate and postgraduate levels. It also draws upon experience gained during research projects and from leading industry experts. It therefore provides non-specialists with a valuable introduction to composite manufacturing techniques, helping to determine the most suitable manufacturing routes and to understand the challenges associated with the production of high-performance composite components. Provides an overview of the most common manufacturing routes for fibre reinforced composites, including the influence of the manufacturing route on mechanical properties, production volume and component cost Discusses recent advances in composite manufacturing, including the use of automation, process simulation, digital factories, and solutions to improve sustainability Looks at where the composites sector is heading and discusses some of the challenges faced by end-users looking to scale up production and increase the uptake of fibre-reinforced composites for structural applications

Multi-scale modelling of composites is a very relevant topic in composites science. This is illustrated by the numerous sessions in the recent European and International Conferences on Composite Materials, but also by the fast developments in multi-scale modelling software tools, developed by large industrial players such as Siemens (Virtual Material Characterization toolkit and MultiMechanics virtual testing software), MSC/e-Xstream (Digimat software), Simulia (micromechanics plug-in in Abaqus), HyperSizer (Multi-scale design of composites), Altair (Altair Multiscale Designer) This book is intended to be an ideal reference on the latest advances in multi-scale modelling of fibre-reinforced polymer composites, that is accessible for both (young) researchers and end users of modelling software. We target three main groups: This book aims at a complete introduction and overview of the state-of-the-art in multi-scale modelling of composites in three axes: • ranging from prediction of homogenized elastic properties to nonlinear material behaviour • ranging from geometrical models for random packing of unidirectional fibres over meso-scale geometries for textile composites to orientation tensors for short fibre composites • ranging from damage modelling of unidirectionally reinforced composites over textile composites to short fibre-reinforced composites The book covers the three most important scales in multi-scale modelling of composites: (i) micro-scale, (ii) meso-scale and (iii) macro-scale. The nano-scale and related atomistic and molecular modelling approaches are deliberately excluded, since the book wants to focus on continuum mechanics and there are already a lot of dedicated books about polymer nanocomposites. A strong focus is put on physics-based damage modelling, in the sense that the chapters devote attention to modelling the different damage mechanisms (matrix cracking, fibre/matrix debonding, delamination, fibre fracture,...) in such a way that the underlying physics of the initiation and growth of these damage modes is respected. The book also gives room to not only discuss the finite element based approaches for multi-scale modelling, but also much faster methods that are popular in industrial software, such as Mean Field Homogenization methods (based on Mori-Tanaka and Eshelby solutions) and variational methods (shear lag theory and more advanced theories). Since the book targets a wide audience, the focus is put on the most common numerical approaches that are used in multi-scale modelling. Very specialized numerical methods like peridynamics modelling, Material Point Method, eXtended Finite Element Method (XFEM), isogeometric analysis, SPH (Smoothed Particle Hydrodynamics),... are excluded. Outline of the book The book is divided in three large parts, well balanced with each a similar number of chapters:

These proceedings present papers on Additive Manufacturing, Composites Forming Processes, Extrusion and Drawing, Forging and Rolling, Formability of Metallic Materials, Friction and Wear in Metal Forming, Incremental and Sheet Metal Forming, Innovative Joining by Forming Technologies, Lionel Fourment MS on Optimization and Inverse Analysis in Forming, Machining and Cutting, Material Behavior Modelling, New and Advanced Numerical Strategies for Material Forming, Non-Conventional Processes, Polymer Processing and Thermomechanical Properties, Sustainability on Material Forming, and Property-Controlled Forming.

The aim of this book is to provide the background of the warp knitting patterning with a large amount of simulated 3D images of the structures, corresponding to the modern available tools for this. The warp knitted structures can have very complex architectures and very limited understanding exists on how they are built. The pattern book will allow

There have been important recent developments in the production and application of three dimensional fabrics. These 3D textile structures have great potential for new fabrics and textile applications. 3D Fibrous Assemblies summarizes key developments and their applications in the textile industry. The book begins with an introductory chapter which defines the concepts and types of 3D fibrous assemblies. The book then discusses how 3D fabrics can be applied in textiles products. These range from composites and protective clothing to medical textiles. The remainder of the book reviews the two main 3D fabrics; multi-axial warp knitted fabrics and multi-layer woven fabrics. Themes such as structure, manufacture, properties and modeling are considered for both fabrics. Written by a distinguished author, 3D Fibrous Assemblies will be a pioneering guide for a broad spectrum of readers, ranging from fiber scientists and designers through to those involved in research and development of new generation textile products.

Annotation This pioneering book presents exciting opportunities for the creation of new textiles through the use of three dimensional textile fibre assemblies. It provides textile industry professionals with a comprehensive account of the different types of 3D fabrics and their associated structure, properties, manufacture and modelling. Particular emphasis is placed on the most important 3D fabrics: multi-axial warp knits and multi-layer woven fabrics. The book provides examples of how three dimensional fibres can be applied in textile products, ranging from reinforcement of composites to automotive and medical applications.
