In the paper a number of computational issues related to the continuum modelling of dynamic failure will be addressed. Attention is focused on the influence of the crack concept. A comparison is made between the standard, the rate-dependent and the gradient-dependent crack concept. The effect of the inclusion of an internal length scale for the latter two models and its influence on the failure mechanism is discussed. The computational analysis of a reinforced beam under impact loading is treated as an example.
