TLDR
In this paper, a total deformation theory of plasticity, in conjunction with two hardening stress-strain relations, is used to determine the dominant singularity at the tip of a crack in a tension field.Abstract:
D istributions of stress occurring at the tip of a crack in a tension field are presented for both plane stress and plane strain. A total deformation theory of plasticity, in conjunction with two hardening stress-strain relations, is used. For applied stress sufficiently low such that the plastic zone is very small relative to the crack length, the dominant singularity can be completely determined with the aid of a path-independent line integral recently given by rice (1967). The amplitude of the tensile stress singularity ahead of the crack is found to be larger in plane strain than in plane stress.read more

Micromechanical elastic cracktip stresses in a fibrous composite
Jacob Fish,N. Fares,A. Nath +2 more
TL;DR: In this paper, the authors present elastic stress distributions near a cracktip in a continuous fiber composite using the finite element method and a new mesh superposition technique, which superposes a fine mesh with heterogeneous material properties over a coarse mesh with homogeneous ones.

J-integral analysis: an EDXD and DIC comparative study for a fatigue crack
TL;DR: In this article, the 2D elastic strain and displacement fields of a propagating fatigue crack in the HAZ of a welded Cr2Ni4MoV bainitic steel were tracked via a phase congruency analysis of the displacement field, and also by detection of its cyclic plastic zone.
