Abstract

This paper concerns a fracture mechanics problem for elastic cracked materials under transient dynamic loading. The nonlinear contact problem for a linear crack under oblique Heaviside compression pulse is solved by the boundary integral equations method in the frequency domain, and the components of the solution are presented by the Fourier exponential series. The contact forces are calculated and the solution is analysed accounting for the friction. The dynamic stress intensity factors are computed at leading and trailing crack’s tips and compared with those obtained neglecting the crack closure and friction.
