Book Description
In this study, the local damage mechanisms and strain fields near the crack tip as well as the crack growth behavior in an centrally-cracked sheet specimen was investigated. The specimen was made of a particulate composite material containing hard particles embedded in a rubbery matrix and it was subjected to a constant strain rate of 0.5/min at room temperature. The effects of the applied strain level on the local damage and fracture processes as well as the strain fields near the crack tip were investigated and the results are discussed.

Book Description
This book explores damage growth and fracture processes in cementitious, ceramic, polymer and metal matrix composites, integrating properties like stiffness and strength with observation at below macroscopic scale. Advances in multiscale modelling and analysis pertain directly to materials which either have a range of relevant microstructural scales, like metals, or do not have a well-defined microstructure, like cementitious or ceramic composites.

Book Description
Written by leading authorities in the field of damage and micromechanics of composites, this book deals mainly with the damage impaired in composites due to different types of loading. It examines the different types of damage in composites in the fiber, matrix, debonding and delamination. It also reviews the theoretical characterization of damage, its experimental determination as well as the numerical simulation of damage.

Book Description
The design of structural systems in the aerospace industry has been characterized by a continuing search for strong, yet lightweight, materials to achieve maximum payload capability for minimum weight. In recent years, this search has led to a wide use of fiber reinforced composites, such as carbon, glass and kevelar based composites. Comparison of these new materials with the traditional ones (metals) according to the basic properties, such as density, elastic modulus and also long-time and short-time strength, shows their superiority over traditional materials, when weight is a major design factor, like in the aerospace industry. Most composite materials of interest to aerospace applications have been adequately characterized under static loading conditions. Related work to study their fracture behaviour has been limited. Since most failure mechanisms involve crack growth and/or delamination, design of such components requires knowledge and understanding of their fracture properties. This thesis includes an experimental and analytical investigation of fracture characteristics of composite materials. The post-peak response of notched specimens subjected to uniaxial cyclic loading is established to evaluate the fracture energy associated with progressive matrix damage and subsequent crack growth. A total of 75 uniaxial tension specimens were tested. The experimental work consisted of first testing several un-notched specimens with different thickness (number of layers) to determine the initial and secondary elastic modulus as well as the tensile strength. The investigation studied the effect of the various fracture parameters, including th ckness, fiber orientation, and crack width ratio ('a'/'w') on the behaviour of crack propagation, peak load, and post-peak response. The specimens used in this research were prepared using the vacuum bagging technique, with a chosen number of fiber glass cloth layers and fiber orientation. The experimental results provided informa.
