The impact responses of rectangular and penny-shaped crack are considered in this study. Laplace-Fourier and Laplace-Hankel transforms are used to reduce the mixed boundary problems to dual integral equations. The solutions are expressed in terms of Fredholm integral equations of the second kind having a kernel with fast rate convergence. The numerical inversion of Laplace transform by the use of the FFT algorithm contributes to the improvement of the accuracy of the result and the reduction of CPU time.
