MODIFIED ADACHI-OKA'S ELASTO-PLASTIC CONSTITUTIVE MODEL FOR SOFT ROCK

Elasto-Plastic Constitutive Model for Finite Element Simulation of structural Adhesives

Considered by the automotive industry as a good solution to bond car body parts together, structural adhesives must be integrated in the early design process of vehicles, hence in the finite element analysis. A first difficulty when modeling structural adhesives comes from their complex mechanical pressure-dependent behaviour as well as their load-dependent strength. These aspects make them imp...

Failure Behavior and Constitutive Model of Weakly Consolidated Soft Rock

Mining areas in western China are mainly located in soft rock strata with poor bearing capacity. In order to make the deformation failure mechanism and strength behavior of weakly consolidated soft mudstone and coal rock hosted in Ili No. 4 mine of Xinjiang area clear, some uniaxial and triaxial compression tests were carried out according to the samples of rocks gathered in the studied area, r...

Nonlinear elasto-plastic model for dense granular flow

This work proposes a model for granular deformation that predicts the stress and velocity profiles in well-developed dense granular flows. Recent models for granular elasticity (Jiang and Liu 2003) and rate-sensitive plastic flow (Jop et al. 2006) are combined into one universal granular continuum law, capable of predicting flowing regions and stagnant zones simultaneously in any arbitrary 3D f...

A Unified Anisotropic Elasto-plastic Model for Sand

This paper presents a unified approach to model the influence of fabric anisotropy 6 and its evolution on both the elastic and plastic responses of sand. A physically based fabric 7 tensor is employed to characterize the anisotropic internal structure of sand. It is incorporated 8 into the nonlinear elastic stiffness tensor to describe anisotropic elasticity, and is further 9 included explicitl...
