文摘

The stress analysis of saturated porous cylinder with penny-shaped crack under normal impact. The formulation is based on the Biot theory and utilizing Fourier and Laplace transforms. The influence of pore fluid on mode-I dynamic stress-intensity factor is determined. The presence of pore fluid is found to affect the magnitude of dynamic stress-intensity factor.
