内容简介
“Strength of Fibrous Composites”addresses evaluation of the strength of a fibrous composite byusing its constituent material properties and its fiberarchitecture parameters. Having gone through the book, a reader isable to predict the progressive failure behavior and ultimatestrength of a fibrous laminate subjected to an arbitrary loadcondition in terms of the constituent fiber and matrix properties,as well as fiber geometric parameters. The book is useful toresearchers and engineers working on design and analysis forcomposite materials.
