Computation of Dynamic Stress Intensity Factor by Direct Integral Boundary Element Method

Abstract:

A linear temporal value of the displacement and stress on the boundary over a time interval is adopted, and the boundary integral equation calculating dynamic SIF (Stress intensity factor) in time domain is set up by the travelling characters of elastic wave and the dynamic extention of Betti’s reciprocal theorem. The dynamic SIF of the cracked finite plate is calculated. The comparison shows that the computational results agree favourably with other published results .
