Calculations of the theoretical strengths of crystalline solids are usually based on idealised forms of atomic force-displacement curves, in which the force is defined as the differential with respect to distance of the inter-atomic or inter-ionic energy. The energy curve is similar to that for a diatomic molecule in that it represents the resultant of

We now turn to the description of the crack behavior. From a macroscopic, continuum mechanical viewpoint, we consider a crack as a cut in a body. Its opposite boundaries are the crack surfaces which are also called crack faces or crack flanks (Fig. 4.1). In general they are traction-free. The crack ends at the crack front or crack tip.

Probabilistic fracture mechanics
2011The failure analysis of a structure proceeds on the basis of a fracture or failure criterion. A typical example is the criterion of brittle fracture K I = K Ic which states that failure does not take place for K I < K Ic . Application of such a criterion in the deterministic sense requires all involved quantities to be exactly known.

So far, our investigations of crack initiation and propagation have always been based on the assumption of quasistatic conditions. This is no longer justified when inertia forces or high strain rates significantly affect the fracture behavior. It is, for instance, well known that a material is more likely to fail under impulsive dynamic loading than in
