The dynamic response of a central crack in a finite elastic strip was considered in this study. The crack was assumed to appear suddenly when the strip is being stretched at its two ends. Laplace and Fourier transform techniques were used to formulate the mathematical solution. Numerical results on the dynamic stress-intensity factor were obtained. The influence of inertia, finite boundaries and their interactions on the load transmission to the crack tip were discussed.
