Analytical and Numerical Homogenization of a Bio-Source Concrete

Abstract

In this paper, we are interested in the analytical homogenization of the elastic properties of concrete with jute fibers of composite material (CJF). Is to characterize the behavior of the concrete reinforced with jute fibers. This behavior will be investigated by using the two-dimensional (2D) nonlinear finite element method, where Ansys commercial software is used as a modeling tool. In order to show the effect of volume fraction Vf on the fibers in concrete, they were modeled as homogeneous isotropic materials. Results obtained from homogenization numérique were close to analytical homogenization results. It was found that the usage of the jute fibers was not significantly enhanced to characterize the behavior because this jute fiber is a weak natural material. The importance of this research is that it shows the ability to use the finite element method to simulate concrete beams reinforced with jute fibers. The results of the numerical approach and the analytical results obtained show that the concrete loaded with 6% of its volume in jute fiber is the most rigid.
