摘要In this study, the dynamic stress intensity factor of a surface crack subjected to an antiplane moving loading is derived. The solution is 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 dislocations on the crack faces and along the crack tip line, respectively. The transient response for stress intensity factor is obtained and expressed in compact formulations. The solutions are valid for an infinite length of time and have accounted for the contributions of an infinite number of diffracted and reflected waves. Numerical calculations for both moving and stationary loading cases are evaluated and discussed in detail. The results indicate that the stress intensity factor will approach the steady-state or static solutions after the first few waves have passed the crack tip.
