Abstract:

An evaluation was made of the applicability of the first-order shear deformation theory (FSDT) to the linear elastic analysis of sandwich plate structures. The plates under investigation were symmetric cross-ply laminates with woven E-glass/vinyl ester composite face sheets and cores of either balsa wood or PVC foam. The FSDT was compared with a solid finite element model approximating a three-dimensional elasticity solution. The static response (deflection and axial strain) under transverse uniform loading and first natural vibration frequency were compared and three values of shear correction factor considered. A simplified model for sandwich plates was also evaluated and the effect of the span/depth ratio and transverse shear modulus of the core material studied. 16 refs.
