โœฆ Synopsis

We formulate an efficient numerical algorithm based on finite-difference approximations and inspired by algorithms from gas dynamics to treat the quasilinear wave equation

governing antiplane motions of incompressible, isotropic nonlinearly elastic bodies in two-dimensions. In particular, we are concerned with the treatment of focusing and shocks for bodies whose material response differs markedly from that of linear elasticity. We carefully validate our method by comparing our results with those of the axisymmetric version of this equation in polar coordinates.

The paper deals with the problem of finding the distribution of stress in the neighbourhood of a Griffith crack located at the interface of two bonded dissimilar elastic half-spaces. The crack is excited by a normally incident antiplane shear wave. The problem is reduced to that of solving a Fredhol

The propagation of a shear surface wave (SSW) along the interface of an elastic half-space liquid and micropolar half-space is considered. The phase velocity of the wave and its attenuation constant are determined. It is shown that a SSW at the interface of a solid and a micropolar liquid propagates
