Families of asymptotic tensile crack tip stress fields in elastic-perfectly plastic single crystals

In this work, two families of asymptotic near-tip stress fields are constructed in an elastic-ideally plastic FCC single crystal under mode I plane strain conditions. A crack is taken to lie on the (010) plane and its front is aligned along the $${[\overline{1}01]}$$ direction. Finite element analysis is first used to systematically examine the stress distributions corresponding to different constraint levels. The general framework developed by …
