Elastic-plastic Analysis of Cracks in Pressure-sensitive Materials
In this paper we present an elastic-plastic analysis of the small-scale yielding crack-tip fields for pressure-sensitibe materials. Mode 1 loading and plane-strain conditions are assumed. The yield criterion is chosen to be a linear combination of the effective stress and the hydrostatic stress. For power-law hardening materials. our elastic-plastic finite element analysis shows that HRRtype cr...
متن کاملOn Stress Analysis for Cracks in Elastic Materials with Voids
The paper deals with classical problem for cracks dislocated in a certain very specific porous elastic material, described by a Cowin-Nunziato model. We propose a method based upon a reducing of stress concentration problem for cracks to some integral equations. By applying Fourier integral transforms the problem is reduced to some integral equations. For the plane-strain problem we operate wit...

We study quasistatic evolution problems for pressure-sensitive plastic materials in the context of small strain associative perfect plasticity.
متن کاملA Semi-analytical Approach to Elastic-plastic Stress Analysis of FGM Pressure Vessels
An analytical method for predicting elastic–plastic stress distribution in a cylindrical pressure vessel has been presented. The vessel material was a ceramic/metal functionally graded material, i.e. a particle–reinforcement composite. It was assumed that the material’s plastic deformation follows an isotropic strain-hardening rule based on the von-Mises yield criterion, and that the vessel was...
متن کاملAsymptotic Analysis of Growing Plane Strain Tensile Cracks in Elastic-ideally Plastic Solids
AN EXACT asymptotic analysis is presented of the stress and deformation fields near the tip of a quasistatically advancing plane strain tensile crack in an elastic-ideally plastic solid. In contrast to previous approximate analyses, no assumptions which reduce the yield condition, n priori, to the form of constant inplane principal shear stress near the crack tip are made, and the analysis is v...
