This book presents the topics of major importance toward understanding the most feared failure mode in composite laminates, namely delamination. There are few books at present that describe the phenomenon of composite laminate failure by delamination in such detail. Written by pioneers and principal researchers in various aspects of composite delamination, starting from basic principles to the most current research findings, the work provides a complete study of the theoretical and experimental aspects of composite delamination in one volume.
