Abstract

A crack instability analysis is presented which allows the maximum load stress intensity factor (K_c) to be predicted from a pre-determined correlation between K_c and a geometric parameter, Φ. Experimental results on asbestos cements are available in the literature and they show that there is a good correlation between k_c and Φ reasonably independent of size effects. However, specimen geometry seems to have some influence on the K_c-Φ relationship. This is suggested to be caused by a geometric effect on the Kr-curve.
