Including effect of bending stress parallel to the crack plane on a developed local limit load model Open
A plate containing a semi-elliptical surface crack is selected as a typical surface crack case to investigate the effects of the bending stress parallel to the crack plane on the limit load and elastic-plastic J. Elastic and elastic-plasti…
