Description
Abstract:	The objective of this study is to develop and verify a theoretically-based method for characterizing mode I delamination fracture of composite laminates. Attention focuses on the special problems associated with delamination of composites with multidirectional (as opposed to unidirectional) layups. Nonlinear beam theory is used to analyze the Double Cantilever Beam specimen to derive an approximate expression for the J integral. A related test method is proposed. An experiment program is described which explores the utility of the method and the variables affecting delamination of multidirectional composites.
