Finite Element Modeling of the Mechanical Behavior of Earth Concrete

Abstract

With the increased awareness of environmental issues, research on earth concrete as an alternative construction material has gained a renewed interest. Compared to conventional concrete, this material is less resistant and hence better knowledge of the mechanical behavior is required. In the present paper, the mechanical response of earth concrete is assessed. Finite elements simulations are performed at the macroscopic scale using Fichant's isotropic damage model in order to have a better understanding of the fracture behavior of these materials and to determine their mechanical properties. The capability of the model is valued by comparing the results of the numerical simulations with the corresponding experimental ones. The results reveal the ability of this damage model to successfully describe the mechanical behavior and performance of earth concrete materials.
