Book Description
The objective of this first part of a 2-year program was to investigate the micromechanical behavior of a fiber-reinforced composite under compressive loadings. In order to improve the compressive strength of composites, the interactions between fibers and matrix must be understood. The approach used for the investigation was both experimental and analytical. Material models and composite specimens under load were observed and test results analytically interpreted. Mathematical equations and terms which describe the micromechanical and elastostatic behavior of the constituent material of a fiber-reinforced composite under compressive loading were analyzed. The fracture theory under compressive load has been developed which includes consideration of shear properties and changes of the effective compressive modulus at high strain and low slenderness ratio. Equations which determine the ultimate compressive strength of a composite were established. Several other related problems of interaction between fibers and matrix have been investigated. (Author).
Mathematical Modeling and Micromechanics of Fiber-Reinforced Bimodulus Composite Materials

Book Description
In Part I of this report are described and evaluated various mathematical constitutive equations proposed to model the mechanical behavior of fiber-reinforced composite materials having different compliances in tension and compression. Five different constitutive equations are described in detail and evaluated in the light of three criteria. In Part II of the report two entirely different micromechanistic approaches are developed to explain these observed differences in tension/compression behavior: the mean-fiber-angle approach originated by Tarnopol'skii et al. and the elastically supported tie-bar/column approach originated by Herrmann et al. (Author).
Micromechanics of Composite Materials

Book Description
Summary: A Generalized Multiscale Analysis Approach brings together comprehensive background information on the multiscale nature of the composite, constituent material behaviour, damage models and key techniques for multiscale modelling, as well as presenting the findings and methods, developed over a lifetime's research, of three leading experts in the field. The unified approach presented in the book for conducting multiscale analysis and design of conventional and smart composite materials is also applicable for structures with complete linear and nonlinear material behavior, with numerous applications provided to illustrate use. Modeling composite behaviour is a key challenge in research and industry; when done efficiently and reliably it can save money, decrease time to market with new innovations and prevent component failure.
Fiber Fracture
Author: M. ElicesPublisher: Elsevier
ISBN: 9780080441047
Category : Science

Book Description
The idea for this book came out of the EURESCO Conference on High Performance Fibers: Euroconference on Fiber Fracture in 2000. Many of the books that are currently available look at different aspects of fiber processing, properties, or applications, but none are focussed on the fracture behaviour of fibers. This book presents the mechancisms and models of fiber fracture currently available for both natural and synthetic fibers, and it is expected that increasingly there will be cross fertilization between the fields, opening new frontiers in academic research and more competitive products for industry. It covers the following areas of fiber fracture: ceramic fibers; glass fibers; carbon filters; metallic fibers and thin wires; polymeric fibers; and carbon nanotubes.
Stress Analysis of Fiber-reinforced Composite Materials

ISBN: 193207886X

Languages : en
Pages : 718
Book Description
Updated and improved, Stress Analysis of Fiber-Reinforced Composite Materials, Hyer's work remains the definitive introduction to the use of mechanics to understand stresses in composites caused by deformations, loading, and temperature changes. In contrast to a materials science approach, Hyer emphasizes the micromechanics of stress and deformation for composite material analysis. The book provides invaluable analytic tools for students and engineers seeking to understand composite properties and failure limits. A key feature is a series of analytic problems continuing throughout the text, starting from relatively simple problems, which are built up step-by-step with accompanying calculations. The problem series uses the same material properties, so the impact of the elastic and thermal expansion properties for a single-layer of FR material on the stress, strains, elastic properties, thermal expansion and failure stress of cross-ply and angle-ply symmetric and unsymmetric laminates can be evaluated. The book shows how thermally induced stresses and strains due to curing, add to or subtract from those due to applied loads.Another important element, and one unique to this book, is an emphasis on the difference between specifying the applied loads, i.e., force and moment results, often the case in practice, versus specifying strains and curvatures and determining the subsequent stresses and force and moment results. This represents a fundamental distinction in solid mechanics.

Book Description
This handbook addresses the needs of those who are involved in inventing, developing, and testing implants and are concerned about the interactions between biomaterial and body tissue. The authors explore the physical, chemical, mechanical and regulatory considerations of synthetic materials used in surgical and implant procedures, and how these factors impact the latest developments and new approaches. This updated edition provides the biomaterials professional with necessary information on a range of issues, including bulk characterization, surface evaluations, toxicological evaluations, in vitro methods for safety evaluation, methods for evaluating materials in special applications, surgical considerations, systems implantology, soft and hard tissue history, regulatory aspects, and clinical trials.
