This second edition includes original methods of analysis for various types of composite materials such as composite beams. The authors provide an entire chapter devoted to thick laminated composites. The first section describes the properties, fabrication process, and applications of composite materials. The second section describes the mechanics of composites, such as the elastic anisotropic properties and mechanical properties of thin laminates. The third section discusses orthotropic coefficients that may be used for design, including the Hill-Tsai failure criterion. The final section provides 43 case studies with solutions that illustrate the challenges encountered in modern engineering practice.
