Progressive failure methodologies for predicting residual strength and life of laminated composites

Content Provider	NASA Technical Reports Server (NTRS)
Author	Harris, Charles E. Allen, David H. Obrien, T. Kevin
Copyright Year	1991
Description	Two progressive failure methodologies currently under development by the Mechanics of Materials Branch at NASA Langley Research Center are discussed. The damage tolerance/fail safety methodology developed by O'Brien is an engineering approach to ensuring adequate durability and damage tolerance by treating only delamination onset and the subsequent delamination accumulation through the laminate thickness. The continuum damage model developed by Allen and Harris employs continuum damage laws to predict laminate strength and life. The philosophy, mechanics framework, and current implementation status of each methodology are presented.
