Static deflection simulation study of 2D Functionally graded porous structure

Abstract

In this study, the two directional graded structure has been developed using a commercial FE package ANSYS and the subsequent deflection responses are obtained. Additionally, the model includes the porosity within the graded structure considering even type of distribution pattern. The present model is derived using the basic steps available in the ANSYS platform through the batch input technique. The comparison study shows that the current simulation model is efficient enough to find out the deflection responses with an insignificant difference between the available results without compromising with its accuracy. Further, the influence of the variable design parameters such as thickness ratio, porosity index, aspect ratio and power-law exponent (nx and nz) on the static responses of the 2D graded structure is obtained. Also, the parametric study shows that the stiffness values are decreasing with an increase in porosity index and the subsequent deflection responses increasing by 25–86%.
