Stress distribution in a five-layer sandwich plate with FG face sheets using layerwise method

Abstract

The effects of functional properties of the face sheets as well as the mechanical properties of the core and other constituents, on stress distribution in a simply supported five-layer sandwich plate are investigated. Layerwise theory (LT) is adapted to solve for stress distribution in each layer based on first-order shear deformation theory (FSDT). Results indicate that LT gives very good estimations on planar stresses in the adhesive layers compared to those of finite element analysis (FEA). The peak in-plane and out-of-plane shear stresses developed at the adhesive interfaces have values much higher than those of the applied load.
