In this paper we develop the governing equations of the coupled damage-plasticity model, which is capable of representing the main mechanisms of inelastic behavior including irreversible plastic deformation, change of elastic response and the localized failure. We show in particular how such model should be implemented within the stress-based variational formulation, providing an important adva...

In the present contribution, capabilities of classical and higher order damage-plasticity continuum models in their ability to predict complex shear failure concrete is assessed. To this end, a local formulation popular Concrete Damage-Plasticity model by Grassl Jirásek (2006a) with mesh-adjusted softening modulus compared gradient-enhanced Poh Swaddiwudhipong (2009) recently proposed micropola...

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 inte...

A gradient-extended two-surface damage-plasticity model based on a von Mises yield criterion has been proposed by [1, 2], which can be flexibly adapted to (quasi-)brittle-like, ductile-like, or various material behaviors in between. However, the does not take into account effect of hydrostatic pressure, therefore it hardly failure behavior pressure-sensitive materials such as geomaterials and s...

The introduction of concrete damage plasticity material models has significantly improved the accuracy with which structural elements can be predicted in terms their response. Research into this method's analyzing complex forms been limited. A model combined a model, based on continuum mechanics, is recommended for effectively predicting and simulating behaviour. parameters, such as compressive...
