Available in PDF, EPUB and Kindle. Book excerpt: Realistic computer prediction of high-velocity impact and penetration events involving composite materials requires a knowledge of the material behavior under large compressive stresses at high rates of deformation. As an aid to the development of constitutive models for composites under these conditions, methods for numerical simulation of the material response at the microstructural level are being developed. At present, the study is confined to glass fiber/epoxy composites. The technique uses a numerical model of a representative sample of the microstructure with randomly distributed fibers. By subjecting the boundary of this numerical sample to prescribed loading histories, a statistical interpretation allows prediction of the global material response. Because the events at the microstructural scale involve locally large deformation, and because of the constantly changing picture with regard to contact between the fibers, the Eulerian code CTH is used for these calculations. Certain aspects of material failure can also be investigated using this approach. The method allows the mechanical behavior of composite materials to be studied with fewer assumptions about constituent behavior and morphology than typically required in analytical efforts.

Download or read book Impact Damages of Braided Composites written by Meiqi Hu and published by Springer Nature. This book was released on 2021-11-30 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports thermo-mechanical coupling constitutive equations and impact damage distributions of 3-D braided composite materials under impulsive loadings, in multidisciplinary fields among mechanical engineering, textile engineering and impact dynamics. The 3-D braided composite is one of the unique textile composites with integrated braided preform structure. Currently the 3-D braided composite has been rapidly applied to aerospace, automotive and medical engineering because the materials could realize the integration of material structure to manufacture complex structural parts and reduce the number of assembly connections. This book presents a thermo-mechanical coupled multiscale geometrical model of the 3-D braiding composite beams and tubes for analyzing damage mechanisms under various impact velocities. Impact deformation and damage morphologies have been described both in experimental observations with high speed cameras, micro-CT and finite element analyses. All the impact damages are shown in figures for unveiling the relationships between microstructure and failure modes. This provides a vivid way for how to design braided structures with high impact damage tolerance. The book is intended for graduate students who are interested in composite materials and mechanics, researchers investigating on impact dynamics of composite structure design, and engineers working on impact-proof structure design. The English translation of this book from its Chinese original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com). A subsequent human revision of the content was done by the author.

Download or read book Dynamic Failure of Materials and Structures written by Arun Shukla and published by Springer Science & Business Media. This book was released on 2009-10-20 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Failure of Materials and Structures discusses the topic of dynamic loadings and their effect on material and structural failure. Since dynamic loading problems are very difficult as compared to their static counterpart, very little information is currently available about dynamic behavior of materials and structures. Topics covered include the response of both metallic as well as polymeric composite materials to blast loading and shock loadings, impact loadings and failure of novel materials under more controlled dynamic loads. These include response of soft materials that are important in practical use but have very limited information available on their dynamic response. Dynamic fragmentation, which has re-emerged in recent years has also been included. Both experimental as well as numerical aspects of material and structural response to dynamic loads are discussed. Written by several key experts in the field, Dynamic Failure of Materials and Structures will appeal to graduate students and researchers studying dynamic loadings within mechanical and civil engineering, as well as in physics and materials science.
