Abstract
In this study, the buckling behavior of orthotropic composite beams with circular, elliptic and square cut-out shape under compression loading has been studied. A simulation based on finite element method has been developed to evaluate critical buckling load and predict the failure around the holes with different shapes. In order to obtain empirical results, specimens were manufactured with symmetric lay-up and different hole shapes. Several key findings and behavioral characteristics are discussed. The results show that specimens without cut-out have the highest critical buckling load and specimens with circular hole have the lowest critical load. The experimental results are well matching with that of FEM solution.
