Displacement Field Due to a Rectangular Tension Crack in a Half-space in Welded Contact with Another Half-space

Abstract

The expressions for the displacements caused by a point tensile dislocation source in a two phase medium are integrated analytically to obtain the displacement field produced by a finite rectangular tensile crack in a homogeneous, isotropic, elastic half-space in welded contact with another elastic half-space. The results are valid for arbitrary values of the Poisson's ratio of the two media and for the arbitrary observer locations. The variation of the displacement field with the distance from the interface as well as with the distance from the fault is studied numerically.

Deformation of Poroelastic Half-Space due to Centre of Dilatation

“…Reference [11] shows the displacements and stresses due to a single force in an elastic half-space in welded contact with another halfspace. Reference [12] shows the displacements and stress fields produced by a centre of explosion in a viscoelastic half-space in welded contact with another elastic halfspace.…”
