The diffuse damage and localized cracking of quasi-brittle materials (ie, rocks and
concretes) under compression can be delineated by a matrix-microcrack system, wherein a …

A new and practical cohesive zone model (CZM) considering the coupling between damage
mechanics and plasticity is proposed to facilitate structural-scale finite-element (FE) …

Integration of the nonlinear stress–strain relationship plays a critical role in the application of
constitutive models to engineering practice. Aiming at the nonlinear integration problems …

A coupled damage-plastic based constitutive model using a traction-separation law is
developed in this study to simulate the behaviour of mortar joints in masonry structural …

In this study, a new traction‐separation based constitutive model for use in finite element
simulation of masonry joints under complex loading conditions is developed for cohesive …

This paper presents a novel 3D constitutive model for concrete that integrates damage and
plasticity mechanisms, while explicitly incorporating low-cycle fatigue (LCF) effects to …

In this study, two state-of-the-art implementations of the rate-dependent Crystal Plasticity
Finite Element Method (CPFEM) as user material subroutines in the finite element solvers …

Layered rocks (LR) exhibit inherent anisotropic stiffness and strength induced by oriented
rough weakness planes, along with stress induced anisotropy and friction related plastic …

Existence and uniqueness of solution of constitutive integration of non-associative plasticity
has been an open issue until it was partly solved in Zheng et al.(2020), where the …

The pore pressure inside oil and gas reservoirs compartmentalized by sealing faults
increases during injection processes. The rise in the pore pressure can induce fault …
