Abstract
Two classes of problems are considered: (i) dynamic analysis of rapidly propagating cracks in finite bodies, of arbitrary shape, wherein linear-elastic material behavior and two-dimensional conditions prevail; (ii) analysis of fatigue growth of cracks near cold-worked fastener holes in two-dimensional bodies involving elastic-plastic materials. In both instances, simple numerical methodologies to imbed analytical asymptotic solutions for singularities in strains/stresses near the propagating crack-tip, and to account for the spatial movement of these singularities along with the crack-tip, are presented. Numerical Solutions of several problems, in both the cases, are presented; and results for appropriate fracture-characterizing parameters for these problems are presented and discussed.
