    Abstract

    Finite-element simulations of rapid crack propagation are presented. An earlier analysis of a crack extending in an infinite body is reviewed, and an unsuccessful attempt to take advantage of a crack-tip singularity element is discussed. Plausible stress-intensity factors are obtained for both constant speed and accelerating cracks in finite sheets; the results are compared to those obtained by other investigators.

    Keywords:

    crack propagation, fracture properties, finite elements, accelerating cracks
