Consistency relations in Nonlinear Fracture Mechanics.

摘要

A single form of consistency relations between generalized forces and displacements for systems exhibiting power-law behavior is presented. The later discussion focuses on certain details regarding applications of the relations to nonlinear fracture mechanics, emphasizing the finite element analysis of a single edge-cracked strip subjected to remote tension under plane strain conditions. Within the last decade there has been observed a serious computational effort towards obtaining numerical solutions to problems of nonlinear fracture mechanics. The handbook formatted reference gives extensive tabulations of important parameters for various configurations, loadings and material behavior, which makes it useful for engineering analysis, and a review of prior work in the field permits its use it as a good starting point for further research.
