Abstract
Results of a ″generation″ study (i. e. , determining the dynamic stress intensity factor for a crack propagation with a given velocity history), using moving singularity-elements, wherein, alternatively, propagating-crack eigenfunctions, static-crack eigenfunctions, or distorted-isoparametric approximations are employed, are reported. The relative accuracies of the three types of moving singular-elements are assessed. Also, results of a ″propagation study″ (i. e. , determining the crack-tip propagation history based on a given dynamic-fracture-toughness versus crack-velocity relation), involving a rectangular double cantilever beam specimen, and their comparison with the previously reported experimental results are included.
