Subject and Keywords:
Transient dynamic stresses around a rectangular crack in an infinite elastic layer sandwiched between two elastic half-spaces are determined. The rectangular crack is situated at the central plane of the layer, and an internal pressure is applied suddenly to its surfaces. Application of the Laplace and Fourier transforms reduces the problem to the solution of a pair of dual integral equations. To solve these equations, the Laplace transformed crack surface displacement is expanded in a double series of functions which are zero outside the crack. The unknown coefficients occurring in that series are solved with the aid of the Schmidt method. Numerical calculations are carried out for the dynamic stress intensity factors.
