Abstract

The paper considers two classes of problems: numerical analysis of stable crack growth under rising load in two-dimensional situations involving elastic-plastic materials, wherein the process is considered to be quasistatic; and dynamic analysis of rapidly running cracks in linear-elastic materials under two-dimensional conditions. In both instances, numerical methodologies to properly account for singularities in strains/stresses near the crack-front, and to account for the spatial movement of these singularities as the cracktip moves, are presented. Numerical solutions for appropriate fracture-characterizing parameters in both the cases are presented and discussed.
