Abstract

A series of dynamic experiments was performed to further investigate the relationship between the stress intensity factor and crack velocity for Homalite 100. Four different specimen geometries made out of the same sheet of Homalite 100 were studied using the technique of photoelasticity. The stress field around the crack tip was represented in terms of a series whose coefficients were evaluated with the multipoint over-deterministic method. The results indicate that the stress field solution depends on the number of terms in the series representation. The stress intensity factor versus crack velocity curves are distinct in the plateau and the transition region for each specimen geometry but merge in the vertical stem region. Finally the results are compared with similar results obtained with the method of caustics. © 1986.
