An efficient finite element method has been developed for the computation of time-dependent stress intensity factors for cracks of Mode I deformation infinite bodies. Quarter point elements are used near the crack tip to approximate the theoretical singularity. Problems considered herein are: the stationary crack subjected to transient loading conditions, and the rapidly propagating crack. The advantages inherent in this method with regard to accuracy and savings in computational costs are discussed.
