Quasi-static Evolution for a Model in Strain Gradient Plasticity
نویسندگان
چکیده
We prove the existence of a quasistatic evolution for a model in strain gradient plasticity proposed by Gurtin and Anand concerning isotropic, plastically irrotational materials under small deformations. This is done by means of the energetic approach to rate-independent evolution problems. Finally we study the asymptotic behavior of the evolution as the strain gradient length scales tend to zero recovering in the limit a quasistatic evolution in perfect plasticity.

Evaluation of behaviour of thick-walled cylinders under high strain rate loading is of great importance because of their many applications. Most of the studies around these structures were performed in the state of static and quasi-static. Therefore, development of analytical model in structures loaded with high rates in dynamic state and in complete plastic domain is valuable. The main purpos...

The coupled damage/plasticity model for meso-level which is ply-level in case of Uni-Directional (UD) Fiber Reinforced Polymers (FRPs) is implemented. The mathematical formulations, particularly the plasticity part, are discussed in a comprehensive manner. The plastic potential is defined in effective stress space and the damage evolution is based on the theory of irreversible thermodynamics. T...
متن کاملA Critical Revisiting of Finite Elasto-Plasticity
We propose a new evolution model for large strain elastoplasticity. In a quasi-static setting the suggested model can be formulated as a variational evolution. We establish existence of a closely related evolution in a regularized context. We then discuss how the proposed model performs in both a rigid-plastic, and a one-dimensional settings and compare the results with those that could be achi...
متن کاملGlobally Stable Quasistatic Evolution for Strain Gradient Plasticity Coupled with Damage
We consider evolutions for a material model which couples scalar damage with strain gradient plasticity, in small strain assumptions. For strain gradient plasticity, we follow the Gurtin-Anand formulation [19]. The aim of the present model is to account for different phenomena: on the one hand the elastic stiffness reduces and the plastic yield surface shrinks due to material’s degradation, on ...
