Note that the crack onset strain depends on the strain rate [18]. This dependence is explained by the inertia of the accommodation processes governing the onset of plasticity and fracture in a loaded material.

WebCracking or pyrolysis, as it is otherwise known, is a complex phenomenon involving many reactions, intermediate species, and final products. In its most basic form it may be thought of dehydrogenation and C–C bond rupture. The reactions are highly endothermic and heat is needed to initiate and sustain them.
