Material Modeling of Concrete

Abstract

The concrete model’s development has started more than 30 years ago. The plasticity-based models enhanced by damage evolution provided the most suitable solution for multiaxial loading conditions. These types of concrete models consist of three main parts: yield function, flow rule, and hardening-softening rule. Damage evolution law is additionally proposed to provide a simulation of stiffness and strength degradation. Besides the model’s accuracy, the possibility of implementing the applicable software solutions is essential. The implemented concrete models into the best-known Finite Element Method (FEM) software are presented with an overview of simulation possibilities.
