Surface singularity and crack propagation
TL;DR: In this article, the authors derived the variational principle governing the displacement distribution on a unit sphere about point 0 of the crack front edge at the surface of an elastic body, using spherical coordinates r, θ, φ and assuming all three displacements to be of the form r λ p p F ( θ, λ ) where p = distance from the singularity line (crack front edge or notch edge) and p = given constant.

Fracture mechanical models of dry slab avalanche release
TL;DR: In this paper, the implied fracture sequence, fracture geometry, time scale of release, and temperature effects are discussed and shown to be consistent with the known facts of dry slab avalanche release.

TL;DR: In this paper, the authors present preliminary results of a numerical finite element study concerned with the elastic deformation field near the point where a crack front edge intersects the surface of an elastic body.

Elastodynamic fields near running cracks by finite elements
TL;DR: In this article, a finite element method is developed for the computation of elastodynamic stress intensity factors at a rapidly moving crack tip, restricted to bodies whose surfaces and two-material interfaces are either parallel to the direction of propagation or are sufficiently remote.

The stresses around a fault or crack in dissimilar media
TL;DR: In this article, the authors investigated the modulus of the singular behavior of the stress remains proportional to the inverse square root of the distance from the point of the crack, but the stresses possess a sharp oscillatory character of the type r^(-1/2) sin (b log r), which seems to be confined quite close to the point, as well as a shear stress along the material joint line.
