Creep and Fracture Characteristics of Materials and Structures at Elevated Temperatures

Abstract

The work under this contract was concentrated in three major areas: the effect of mixed mode loading on fracture characteristics, the nature of crack tip stress, strain and energy fields in ductile materials and the nature of crack tip stress strain and energy fields in materials undergoing rate dependent viscoplastic deformation. In each of these areas, new insight was obtained and better understanding of the fundamental physical processes gained. The appendices of this work document the significant research contribution that was made under ONR contract N00014-84-K-0027.
