Analysis of static and free vibration of the sandwich folded plate using the Layerwise theory

Abstract

In this paper, the static and free vibration analyses of the sandwich folded plate modeled by layer-wise (LW) theory are studied. In the theory, the continuity displacement condition is imposed at the layer’s interfaces. Each layer of the plate is modeled by the first-order shear deformation theory (FSDT). The numerical solutions are obtained by using the cellbased smoothed discrete shear gap method (CS-DSG3). Some examples are implemented to demonstrate the accuracy of the LW theory for the sandwich folded plate analyses.
