DYNAMIC FRACTURE ANALYSIS: A TRANSLATING-SINGULARITY FINITE ELEMENT PROCEDURE
In this paper an efficient finite element method, which accounts for the translating singularities near the tip of a dynamically propagating crack, is presented. Two aspects of analyses of dynamic fracture, namely, (i) determination of dynamic stress-intensity factors from given crack velocity history, and (ii) determination of crack-velocity history (and arrest) from given dynamic-fracture-toughness versus crack-velocity data are considered. Results are presented and discussed for wedge-loaded rectangular, as well as tapered, double-cantilever beam specimens.
