Abstract

This paper seeks to analyze numerically the mechanical behavior of plates made of two composites materials submitted to bending caused by an uniform transverse static loading, when compared to the behavior of an isotropic material plate. Plates with a centered elliptical hole are considered in this study. According to Constructal Design method, this elliptical hole can vary as a function of the parameter H0/L0 (ratio between semi-axes of the ellipse). However, the ratio between hole volume and plate volume (f) is kept constant. Thus it is possible to evaluate the influence of the hole geometry on the mechanical behavior of the plate with the objective of minimizing the deflection suffered by the plate. In addition, plates with three different kinds of boundary conditions were considered: simply supported on four sides, clamped on four sides and simply supported on two opposite sides and clamped on the other two. A computational model developed in ANSYS software, which is based on the Finite Element Method (FEM), was used to numerically simulate the bending on the plates. The results showed that the hole geometry has a significant influence on the performance of plates as structural components. Improvements up to approximately 115% were obtained for the maximum deflection of the plate.
