| Abstract: |
| According to the present experimental result, the stress-strain relation under different confining pressures has been analyzed; based on the thermodynamics theory, a new constitutive law of concrete is established with the introduction of this modeling in detail. In this modelling, the failure function and mechanical damage criteria highly depends on the stress state. The model’s parameters are determined from conventional triaxial tests. Numerical simulation shows that this elasto-plastical damage model for concrete can well explicit the main mechanical behavior of concrete for a large range of stress and it has a good agreement with the experimental data. |
