TL;DR: In this paper, a quasistatic gradient damage model was used to perform large-scale numerical simulations showing that the propagation of fully developed cracks follows Griffith criterion and depends only on the fracture toughness, while crack morphogenesis is driven by the material's internal length.

TL;DR: In this article, the authors studied the initiation of cracks in the thermal shock problem through the variational analysis of the quasi-static evolution of a gradient damage model and derived the periodic distribution of so-initiated cracks and calculated the crack spacing in terms of the material and loading parameters.

TL;DR: In this article, a generalized Rice path integral is introduced to study the evolution of damage in a two-dimensional setting. But the analysis is made in a 2D setting, assuming that damage is concentrated inside thin bands whose width is proportional to the internal length of the material.

TL;DR: In this article, the authors studied the nucleation and propagation of thermal cracks following a severe thermal shock in gas storage caverns leached out from a salt formation, and showed that cracks nucleate on the rock wall with periodic spacing.
