摘要：The paper deals with a numerical approach of mode-frequency analysis of a simply-supported laminated doubly curved shell. For laminated shell the first-order shear deformation theory is capable of accurately predicting the shell behaviour. Linear layered structural shell elements are used in FEM analysis. The numerical analysis is conducted to determine the effect of symmetry with respect to mid-plane, fibre orientation and width-to-thickness ratio to change of resonant frequencies in the case of angle-ply and crossply laminate.
