Fig. 1. The J-R curves obtained with SE(T) specimens for a) a high strength low alloy steel, and b) an Alloy 52 DMW. The crack back-up is probably caused by friction in the system.

Fig. 2. Predicted and measured a) initial crack length and b) crack growth.

Fig. 3. a) Measured and predicted compliance as a function of a/W. B e is effective thickness. b) The longer the final crack length, the larger is the deformation of the remaining ligament.
