Effect of skew angle on free vibration responses of sandwich composite plate

Abstract

In the present article, the free vibration behaviour of the shear deformable skew sandwich composite plate is examined numerically by using the finite element technique. The plate model is created utilizing higher-order shear deformable hypothesis to evade the shear correction factor. The convergence and the validation of the model have been studied by measuring various types of case accessible in literature. From the examination study, it can be effectively assumed that the currently suggested and established model is equipped for explaining the skew sandwich structures with satisfactory precision including the geometrical complexities. Hence, the model is stretched out to analyze the impacts of the different geometrical parameters, for example, thickness proportion, skew angle, lamination sequence, and end condition on the vibration behavior of the skew sandwich composite plate.
