Although mode I and mode II crack propagation show many similarities, in particular when analysed by linear elastic fracture mechanics, they differ significantly in the micro-structural behaviour. These differences, which are clearly noticeable in th

In general, numerical determination of T-stresses requires careful handling, because of their location in the vicinity of singular points. Discretization methods, such as common finite element methods, may not lead to accurate results. However, the w

A Barenblatt model of the dissipative region at the edge of a mode I crack under small scale yielding is established, so that stress gradient and displacement gradient continuity prevail along the symmetry plane. The resulting model thus connects smo

An analytic solution is given for intersonic mode II crack acceleration. The solution is obtained by first considering a self-similar problem, motion of a semi-infinite crack at constant velocity, under the action of a constant crack face load, appea

Intersonic crack propagation is found to exhibit essentially the same features in orthotropic and isotropic materials, provided that the crack propagates along a plane of elastic symmetry. Thus the stress and strain singularity at the crack edge is w

The discussion is based on the cell model of materials. Each cell contains one dominant kernel of micro-separation, for instance a particle. A cell is either in a cohesive or a decohesive state, the latter implying instability at load control. The pr

The cell is regarded as the smallest material unit that contains reasonably sufficient information about crack growth in the material. A cell is either in a cohesive state or in a decohesive state, the latter implying instability at load control. It

The assumption of a material specific relation between the energy dissipation at the edge of a crack propagating under small scale yielding conditions leads to upper limits of the crack velocity: the Rayleigh wave velocity for modes I and II, and the

Virtually all methods in fracture mechanics seem to be dependent on the existence of an autonomous region near the crack edge, a region in which the processes are dependent on the material rather than on the body and loading geometry. This, usually t
