Buckling analysis of composite plate with central elliptical cut out

Abstract EN

In this study, the multilayer composite plates consist from aluminum, brass, and steel with unsaturated polyester Resin (UPE) as a core material.

The plates having a central circular, elliptical holes.

The buckling parameters such as aspect ratios and different hole orientation angles have been analyzed numerically.

These parameters have been applied at different layers of materials both metallic and non metallic.

Analyses were carried out using finite element method (FEM) through the application of special numerical program written in APDL by ANSYS software.

Result shows that the buckling load were highly dependent on the type of composite material, and the buckling load increased by increasing elliptical hole orientation angle.

Increasing of major and minor diameters of elliptical holes with plate b / w ratios were decrease the buckling load for the multilayer composite plate.
