Abstract:
The elasto-plastic model for concrete is presented in the paper. Though huge number of such models was developed in recent years and even more advanced approach is popular at present, elasto-plasticity still can be useful in structural analysis domain due to explicit physical meaning of material parameters, which can be easily determined on the basis of laboratory tests. Simple implementation in computational systems for analysis of big structural tasks including 3D problems is another advantage of this approach. The model presented here is assigned mainly for he analysis of 3D problems, thus all formulas and procedures are given in form valid for complex stress state. The failure criterion refers to well known Willam-Warnke 3-parameter model. Slight modifications of this model justify the acronym MWW3 and remove some shortcomings of the original Willam-Warnke proposal. Full description of the model includes:
