Abstract

A new ply dependent shear deformation model based on a priori assumed slopes of transverse shear stresses is developed. The performance of the present model relative to that of an earlier model [1,2] is assessed by a comparison with the exact elasticity solutions. The present model is found to be in good agreement with the exact elasticity distributions of the displacements and stresses. The flexural frequencies predicted by the present model are lower than the corresponding estimates from the CPT, HSDT and the earlier model [1,2]. In the case of thickness twist mode frequencies, the estimates provided by the present model are found to be significantly different from those obtained by using the other models.
