摘要 | In this study, the transient response of a surface crack in an elastic solid subjected to a dynamic anti-plane concentrated loading is investigated. The angles of the surface crack and the half-plane are 60.degree. and 90.degree.. The solutions are determined by superposition of the proposed fundamental solution in the Laplace transform domain and by using the method of image. The exact transient closed form solutions of dynamic stress intensity factor are obtained and expressed in very simple and compact formulations. The explicit value of the dynamic overshot for the perpendicular surface crack is obtained from the analysis. Numerical results are evaluated which indicate that the dynamic stress intensity factors will oscillate near the correspondent static values after the first three or six waves have passed the crack tip. |
