Buckling analysis of laminated composites considering the effect of orthotropic material

Abstract

In this work, the simplified forms of governing differential equations are employed to analyse the laminated composite plates subjected to buckling. Effect of orthotropic material via variation in the E1/E2 ratio on the buckling parameters is verified and corresponding results are provided. With the developments in the modern technology, composites have found a significant role in applications in aerospace industry. Under the compressive in-plane loads, the composites undergo buckling. Hence, it is crucial to observe and study the buckling characteristics of laminated composites with effect of material properties. We have obtained the results of the buckling loads of a laminated composite having a cross-ply lamination scheme of plates with simply supported and clamped boundary conditions. Effect of the orthotropic material on these parameters is studied via the present study.
