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

On the process zone of a quasi-static growing tensile crack with power-law elastic-plastic damage*
TL;DR: In this article, a parametric analysis of growing crack tip fields under quasi-static tensile loading with damage coupled power-law elastic-plastic constitutive equations is presented.
Cohesive Zone Modelling in Adhesively Bonded Joints: Analysis on crack propagation in adhe-sives and adherends
TL;DR: In this article, a composite Cracked Lap Shear (CLS) specimen was tested with results of a possible crack jump from bondline to adherend, and the results of the current simulation setups were unsatisfying as the failure load and strain results had large errors.

Thermographic evaluation of metal crack propagation during cyclic loading
TL;DR: In this article, an analytical relationship between the stress intensity factor and temperature rise for a moving crack tip is proposed, which reveals the potential of applying theromographical technique for assessing the behavior of crack growth.

On configurational forces at boundaries in fracture mechanics
TL;DR: In this paper, the authors derived expressions for the surface configurational forces and determined their values on regions of the external boundaries with prescribed tractions or displacements, and determined the relation between the far-field J-integral and the surface configuration forces.

The mathematical theory of plasticity
TL;DR: In this paper, the solution of two-dimensional non-steady motion problems in two dimensions is studied. But the solution is not a solution to the problem in three dimensions.
