Buckling Analysis of Composite Cylinders Subjected to Axial Compressive Loads

Abstract

Slender structures will buckle when subjected to pressure or compressive loads. Buckling is also important factor to decide the failure of the structure. Generally columns and higher length cylinders will buckle and they will be manufactured by the metals. In the present work slender cylinder subjected to axial compressive load manufactured by different composite materials is analyzed. The effect of cylinder length to thickness ratio, materials and stacking angle are analyzed. It results that as the cylinder length to thickness ratio is increasing, the buckling load is decreasing and carbon epoxy woven fabric with stacking angle of 90 o shows higher buckling load.

Post-Buckling Analysis of E-Glass Fiber Reinforced Thin-Walled Cylindrical Composite

“…An initial geometric imperfection has been widely reported to be a single dominant factor, which contributed to the discrepancy between theories and experiments [9][10][11][12][13]. Kumar et al [14] predicted Nonlinear-buckling analysis as a better method and suggested it for calculation or estimation of actual structures. Peining et al [15] points out that stiffness eccentricity is a major factor that causes axial buckling than the combined load.…”
