Abstract An attempt to quantify post-yield fracture in polymers has been made by examining the growth rates of diamond cavities in cold-drawn polycarbonate. The application of the basic principles of fracture mechanics show that the growth rate is extremely stress sensitive. Also, a simple Eyring equation, based on the net section stress, appears to fit the available data. The “activation volumes” derived from the crack growth and neck propagation are of the same order which suggests that the rate of simple shear yielding adjacent to the cavity controls the growth rate.
