Constitutive Model for Multi-laminate Induced Anisotropic Double Hardening Elastic-plasticity of Sand

A constitutive multi-laminate based elastic-plastic model developed to be capable of accounting induced anisotropic behavior of granular material such as sand. The fabric feature or grain orientation characteristic effects through medium are considered in a rational way under any complex stress path, including cyclic loading. The salient feature of the developed model is a non-associative on pl...

Coupling discrete dislocation dynamics with polycrystal plasticity

Lebensohn et al. [1] recently introduced an alternative description of crystal plasticity based on a fast-Fourier transform (FFT) algorithm. The FFT approach solves for the equilibrium stress and strains under the constraint of strain compatibility for systems with periodic microstructures. As currently developed, the FFT model describes plasticity with a set of elasto-viscoplastic constitutive...

Insight into a model for large strain anisotropic elasto-plasticity

Efficient and accurate simulation of the deformations in anisotropic metallic sheets requires a constitutive model and an accompanying algorithm at large strains which take into account the anisotropy of both the elastic and plastic material behaviors, as well as their evolution with plastic strains. Recently we proposed such a constitutive model based on continuum energy considerations, the Le...

A two-surface anisotropic damage/plasticity model for plain concrete

Concrete is a material whose performance is governed by the subtle interaction of its cohesive and frictional constituents. Since the theories of plasticity, damage mechanics, and fracture mechanics cannot, by themselves, capture both of these phenomena, a novel constitutive model is proposed which combines the theories of plasticity and damage mechanics in a multi-surface formulation. Synthesi...

Comparison of two integration schemes for a micropolar plasticity model

Micropolar plasticity provides the capability to carry out post-failure simulations of geo-structures due to microstructural considerations and embedded length scale in its formulation. An essential part of the numerical implementation of a micropolar plasticity model is the integration of the rate constitutive equations. Efficiency and robustness of the implementation hinge on the type of int...
