Abstract

Effects of the crack velocity à and the crack acceleration ä on the dynamic stress intensity factor K_d of Homalite-100 were studied. Evaluations of A_d à and ä during dynamic crack propagation were made by using the method of caustics in combination with high-speed photography. The relation between K_d and à, i. e. K_d(à), showed that it is not a unique function of à and that the decelerating cracks have larger values of K_d(à) than the accelerating cracks for the same velocities. It is found that Ku(à) for a constant acceleration, i. e. Kd(ä =const), becomes a unique function with respect to a.
