Mode-frequency analysis of doubly curved composite laminated shell

Abstract

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.

Effect of large deflection on laminated composite plates

“…Kormanikova presented a numerical approach of mode-frequency analysis of a simply-supported laminated doubly curved shell. For the laminated shell, the first-order shear deformation theory is stated that accurately predicting shell behavior [9]. Dynamic analogues of von Karman-Donnell type shell equations for doubly curved, thin isotropic shells in rectangular platform are formulated and expressed in displacement components by Nath and Sandeep [10].…”
