Concrete is a quasi-brittle material and shows different behavior in compression tension. It elastic at initial stage damage-plasticity beyond limit. Therefore, development of model concrete complex phenomenon. In this study, damage plasticity theory has been described under experiment on cylinder considering uni-axial loading interpreted with analytical data calculated using CEB-FIP code equat...

Neurocomputational modeling has suggested that a range of mechanisms can lead to reductions in functional plasticity across development (Thomas & Johnson, 2006). In this paper, we consider whether ageing might also produce a reduction in plasticity. Marchman’s (1993) model of damage and recovery in past tense formation was extended to incorporate the two main proposals for implementing effects ...

We introduce a continuous damage fiber bundle model and compare its behavior with that of dry fiber bundles. Several interesting constitutive behaviors, such as plasticity, are found in this model depending on the value of the damage parameter and on the form of the disorder distribution. We compare the constitutive behavior of global load transfer models, obtained analytically, with local load...

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 ...

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...

Sheet metal forming as well mechanical joining demand increasingly accurate and efficient material modelling to capture large deformations, the inherent sheet orthotropy even process-induced damage, which is expected be influential. To account for strains additive logarithmic strain space utilised that enables a straightforward incorporation of plastic anisotropy, herein modelled by Hill48 yiel...
