Abstract
A model originally developed to simulate crack propagation in structural steel has been evaluated for porous compacted specimens of aspirin. The fracture mechanism is assumed to consist of hole growth and coalescence. The program allows both visualization of crack growth and the calculation of crack velocity. Simulations to investigate the effect of stress intensity factor indicate that the critical stress intensity factor for sustained growth for aspirin is of the order of 0.15 MPa m1/2 consistent with experimental findings. The program is easy to use enabling many simulations to be performed with minimum effort.
