Abstract

In this paper thermo-elastic stability characteristics of laminated noncircular cylindrical shells subjected to uniform temperature rise are studied using higher order kinematics which accounts for the transverse shear and transverse normal deformations, and incorporates realistic through the thickness approximations of the in-plane displacements. The governing equations obtained through the minimization of total potential energy are solved using finite element approach. The strain-displacement relations are accurately introduced in the formulation. The combined influence of higher-order shear deformation, shell geometry and non-circularity on the critical temperature parameter of oval shells as an example of non-circular shell is examined.
