TL;DR: In this article, a micromechanics-based modification of the Gurson criterion for porous media subjected to arbitrary loadings is proposed, which consists in the consideration of Eshelby-like exterior point trial velocity fields for determination of the macroscopic dissipation.
Abstract: In this study, we propose a micromechanics-based modification of the Gurson criterion for porous media subjected to arbitrary loadings. The proposed formulation, derived in the framework of limit analysis, consists in the consideration of Eshelby-like exterior point trial velocity fields for the determination of the macroscopic dissipation. This approach is implemented for perfectly plastic rigid von Mises matrix containing spherical voids. After the minimization procedure required by the use of the Eshelby-like trial velocity fields, we derive a two-field estimate of the macroscopic yield function. It is shown that the obtained closed-form estimate provides a significant modification of the Gurson criterion, particularly in the domain of low stress triaxialities. This estimate is first compared with existing criteria. Moreover, its accuracy is assessed through comparison with results derived from numerical exact two-field criterion and with recently available numerical bounds.

TL;DR: In this paper, a cantilever assembly subjected to heating at its fixed end, which resembles the welding of a sheet metal is considered, and a control volume approach is introduced for numerical solution of heat transfer equations while the finite element method is adopted for stress field predictions.

TL;DR: In this paper, a spatially continuous, time discrete formulation of the loading of an elastic, perfectly plastic body governed by a von Mises yield condition is presented, where incremental changes in strain occur along minimum work paths, which is equivalent to a backward difference implicit integration algorithm or the radial return method.
Abstract: A spatially continuous, time discrete formulation of the loading of an elastic, perfectly plastic body governed by a von Mises yield condition is presented. It is assumed that incremental changes in strain occur along minimum work paths, which is equivalent to a backward difference implicit integration algorithm or the radial return method.
