Linear and Non-linear Buckling Testing on Aluminium Structures

Abstract

In this paper, cylindrical aluminium structures are tested for examination of buckling phenomenon. Testing of the material structures are accomplished by comparison made on the basis of linearity and non-linearity. The computation of various parameters viz. displacement, external work done, energy loss, and total energy consumed are being performed to evaluate the performance and optimal operating conditions of the aluminium structure. The results are visualized with ABAQUS CAE software. It is observed that non-linear buckling is found superior in terms of structural deformations and energy loss as compared to linear buckling. This non-linear buckling has proved to be an eminent technique to reduce the adverse effects of the buckling phenomenon prominent in aluminium structures.
