This book provides a complete introduction to the mechanical behavior of composite materials. The second edition offers complete introductory treatment of polymer matrix, metal matrix, ceramic matrix, and carbon-carbon matrix composites. It details micromechanical analysis of a lamina, and macromechanical analysis of lamina and laminate. Included are Hooke's law, angle lamina, failure theories, hygrothermal response, laminate design, and beams. An updated version of Promal, the software package included in the first edition, is also included. Promal, available on a supported website, allows readers to conduct studies, compare theories, and quickly assess the information in tables and graphs.
