Path-Independent Integrals in Dynamic Fracture Mechanics,

Abstract

We first consider linear elastodynamic crack propagation under mixed mode non-steady conditions with an arbitrary velocity. Now we consider the problem of analyzing crack-propagation in an arbitrary body, the shape of which and the loading on which, we suppose, preclude any possibility of an analytical solution. Suppose that we have to use a numerical solution. Such a numerical solution may be based on a 'propagating singular-element' within which the asymptotic mixed made solution is embedded; and hence the K-factors can be evaluated directly, as demonstrated by the authors.
