Abstract

Buckling is a condition where an object experiences bending or bending due to the application of a load or compression force (pressure) on the object. Buckling often occurs in thin-walled structures such as plates, shells and so on. The study aims to determine the buckling strength of isotropic and quasi-isotropic plates. The method used is the Finite Element Method (FEM). The techniques used to collect data are literature studies and studies of several similar studies. The material used for isotropic is Aluminum 2024-T3 and for Quasi-Isotropic materials using Carbon/Epoxy T300-5208 with a laminate arrangement of [0°/90°/45°/-45°]s. From the data obtained, modeling and analysis will be carried out using the MSC Patran/Nastran 2012 software. The results of the buckling analysis that have been carried out show that the critical buckling stress value on the isotropic plate is 5.387 · 106 N/m2 and on the quasi-isotropic plate is 5.036 · 106 N/m2 and is still within safe limits when viewed from the Buckling Load Factor (BFL) with a value of >1.
