| Abstract: | In this paper, the transient response of two interface cracks, in a layered half space subjected to antiplane stress fields, is analytically studied. The problem is formulated in terms of a coupled set of integral equations, which are then solved by expanding the unknown crack opening displacements in a complete set of Chebyshev's polynomials. The method is coded in FORTRAN program and numerical results for a sample problem are presented. The results show that the response of one crack is significantly influenced by the presence of a bigger neighboring crack. |
