Buckling analysis of Laminated Composite plates

Abstract

Laminated composites have been used in many engineering structures from early time the recent advancements in material technology has led to the creation of a new composite with enhanced properties. Composite materials are generally used in many fields of engineering like buildings, bridges, boat hulls, swimming pool panels, race car bodies, shower stalls, bathtubs and storage tanks. In addition to that industries where weight reduction is of prime concern (aviation and spacecraft etc.). Composites are capable enough to take different types of loading both tensile and compressive based on the requirement. It is well known that the structural elements under compressive loads and/or due to thin built up they may be prone to buckle. In order to evaluate the buckling strength of laminated structures many studies has already been completed numerically and experimentally. A lab scale buckling test rig has been developed to obtain the critical load. In addition to that a simulation study has been done in ANSYS using ANSYS parametric design language. Some new results have been obtained for different parameter and discussed in detail
