Abstract : We first consider linear elastodynamic crack propagation under mixed mode nonsteady conditions with an arbitrary velocity. Now we consider the problem of analyzing crackpropagation 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 singularelement' within which the asymptotic mixed made solution is embedded; and hence the Kfactors can be evaluated directly, as demonstrated by the authors.
