Stress Concentration of Laminated Composite Plate Containing Circular Hole | Original Article
In this study, an attempt has been made to understand the effect of stress concentration in different laminated composite (Graphite-epoxy, Glass-epoxy, Boron-epoxy) plates with single circular hole subjected to uniaxial tension and pure shear. Mathematical formulations are generated by using MATLAB simulation tool. The effect of fiber orientation, E1/E2 ratios on the stress concentration of the laminated composite plate with a central circular hole is investigated. ANSYS FEM tool is used to understand the effect of geometrical parameters on the stress distribution around the circular hole. Ratio of the diameter of hole to length (D/L) and width (D/A) of the orthotropic plate are analysed.
