摘要Abstract- In this study, the transient response for diffraction of a horizontally polarized shear wave of arbitrary shape by a
finite crack in an elastic solid is investigated. In analyzing .this problem, an infinite number of diffracted waves generated by two
crack tips must be take into account and it will make the analysis extremely difficult. The solutions are determined by
superposition of proposed fundamental solutions in the Laplace transform domain. The fundamental solutions to be used are the
problems for applying exponentially distributed traction and screw dislocation on the crack faces and along the crack tip line,
respectively. The exact transient closed form solutions of dynamic stress intensity factor for two crack tips are obtained and
expressed in very simple and compact formulations. The solutions are valid for an infinite length of time and have accounte~ for
the contributions of an infinite number of diffracted waves. Numerical results for both tips are evaluated which indicate that the
dynamic stress intensity factors will oscillate near the correspondent static values after the first three waves have passed' the
specified crack tip.
