This book was released on 2019-03-22 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a set of tutorials and exercises that I have developed over a number of years as a part of a Master's level course on composites modelling. It is also intended to complement a textbook that I recently published that covers theoretical aspect of these topics. The aim of these tutorials is to introduce the student to some analysis possibilities for engineering composites using, mostly, the general-purpose finite element (FE) method with codes that are freely available on the web and suitable for student study. The first tutorials introduce FE meshing and apply some different material models for isotropic and composites analysis. More advanced composite models with failure are then presented and applied to a 2D and 3D structure. Some different solution methods are covered including linear and non-linear implicit analysis and explicit analysis, and some advanced topics include contact and linear eigenvalues analysis for frequency and buckling problems. Classical laminate analysis and micromechanics coupled to textile mechanics are also covered, with the last two tutorials studying kinematic and FE drape simulation and infusion analysis for manufacturing. Each tutorial is self-contained and has worked examples and student exercises that should take about two hours to complete. I have tried to organise these so that no previous knowledge is required to get started and then progress through to more challenging analyses. Within each tutorial I have added some relevant background information to help understanding of the topic being covered. The author Anthony Pickett undertook postgraduate research in FRP composites at the University of Surrey and RAE Farnborough, followed by nearly twenty-five years industrial work as scientific director with ESI GmbH developing and applying FE codes for process and mechanical simulation of metal and composite structures. From 2002 he was a professor in the composites group at Cranfield University and since 2007 has continued research and teaching of advanced composites at IFB (Institute of Aircraft Design) at the University of Stuttgart. The contents of this book are largely based on teaching material presented to master's level students over the past fifteen years. He is a fellow of the Institute of Mechanical Engineers and the Institute of Materials, and a chartered engineer in the UK, with many publications and several book chapters related to process, impact and crash modelling of composites.

Book excerpt: This book presents a set of tutorials and exercises that I have developed over a number of years as part of a Master's level course on composites modelling. It is also intended to complement a textbook that I recently published covering theoretical aspects and analysis of composites manufacturing (process) and mechanical modelling. The aim of these tutorials is to introduce the student to analysis possibilities for engineering composites using, mostly, the general-purpose finite element (FE) method. The first tutorials introduce FE meshing and apply some different material models for isotropic and composites analysis. More advanced composite models with failure are then presented and applied to a 2D and 3D structure. Different solution methods are covered including linear and non-linear implicit analysis and explicit analysis, and some advanced topics include contact and linear eigenvalue analysis for frequency and buckling problems. Classical laminate analysis is also covered, and the last three tutorials study textile mechanics with TEXGEN, kinematic and FE drape simulation and infusion analysis for manufacturing. I am aware that licensing can be difficult for any student who would like to experiment with commercial software. For this reason, I have selected codes that are easily accessible from the web and suitable for student study. These include the open-source FreeCAD and general purpose CalculiX FE codes. Several tutorials apply LS-DYNA which does require a license; however, this code has a free pre- and post-processor so models can be built, and I have provided a website with all datasets and results files so post processing is also possible. LSTC, who develop LS-DYNA, do have special conditions for student licenses. The other laminate analysis, meshing and drape codes are freely available, and LIMS, which is used for FE composites infusion analysis is available for academic studies. It is hoped that knowledge gained from these tutorials will provide a useful starting point for composites analysis with other codes and help to better appreciate their capabilities. Each tutorial is self-contained and has worked examples and student exercises that should take about two hours to complete. I have tried to organise these so that no previous knowledge is required to get started and then progress through to more challenging analyses. Within each tutorial I have added some relevant background information to help understanding of the topic being covered.

This book was released on 2018-05-15 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering fibre reinforced polymer FRP composites offer many advantages compared to isotopic metals, but their versatility also creates difficulties for their effective manufacture and design. Selection of the right fibre matrix combination for a specific application must consider many factors, not least cost, performance, recyclability and suitability to environmental conditions. Closely linked to these will be selection of the most suitable manufacturing route with further choices regarding desired production volume, cycle time and final part quality. This book in not primarily intended as a design guide to address these requirements, but rather to introduce the reader to modern analysis methods that undertake both process and mechanical analysis of advanced composites for composites design. Chapters are structured to introduce key topics, including an overview on composites and their analysis, micromechanics, macromechanical laminate analysis and two chapters dedicated to finite element FE theory with a focus on composites. This provides the background for chapters dedicated to process modelling of draping, forming and infusion, followed by mechanical modelling of failure, impact and crash. Throughout the book necessary theory, experimental methods, constitutive modelling and numerical methods are elaborated. With applications and worked examples included to help exemplify the theory and numerical methods applied. The book is intended for graduate and post graduate students requiring a broad understanding of modern numerical method for engineering FRP composites analysis. It will also provide a comprehensive overview for researchers and practising engineers in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Themethodologyfordesigninghigh-performancecompositestructuresisstill evo- ing. The complexity of the response of composite materials and the dif?culties in predicting the composite material properties from the basic properties of the c- stituents result in the need for a well-planned and exhaustive test program. The recommended practice to mitigate the technological risks associated with advanced composite materials is to substantiate the performance and durability of the design in a sequence of steps known as the Building Block Approach. The Building Block Approach ensures that cost and performance objectives are met by testing greater numbers of smaller, less expensive specimens. In this way, technology risks are assessed early in the program. In addition, the knowledge acquired at a given level of structural complexity is built up before progressing to a level of increased complexity. Achieving substantiation of structural performance by testing alone can be p- hibitively expensive because of the number of specimens and components required to characterize all material systems, loading scenarios and boundary conditions. Building Block Approachprogramscan achieve signi?cant cost reductionsby se- ing a synergy between testing and analysis. The more the development relies on analysis, the less expensive it becomes. The use of advanced computational models for the prediction of the mechanical response of composite structures can replace some of the mechanical tests and can signi?cantly reduce the cost of designing with composites while providing to the engineers the information necessary to achieve an optimized design.
