Abstract
The material covered in this study was developed in our previous studies. It is a composite of Iroko wood and high-density polyethylene. The objective is to find a way to predict the mechanical behavior during bending. Two studies were conducted: an analytical approach and a simulation using Cast3M. At the end, we compared the respective results. The analytical study confirmed the simulation results. For example, for a 10% high-density polyethylene content, the respective values for the analytical study and the simulation for the cantilever beam with a force applied to the free end are 1.65 x 10-5 and 1.66 x 10-5 degrees for rotation, respectively. For deflection, the respective values are 2.2 x 10-6 and 2.1 x 10-6 m. In construction, this material can be used to make partitions with light loads.
Thus, we obtained a simulation method to predict the bending behavior of this material.
