THERMOELASTIC ANALYSIS OF DOUBLY-CURVED LAMINATED SHELLS

Based on three-dimensional elasticity without making static and kinema tic assumptions, an asymptotic theory is formulated for thermoelastic analysis of doubly curved laminated shells. The laminated shell is reg arded as a heterogeneous shelf with nonhomogeneous material properties in the thickness direction. The bending of the shell subjected to tem perature variations through the thickness and under lateral loads is c onsidered Upon introducing a small perturbation parameter in the formu lation and rearranging the three-dimensional equations in dimensionles s forms it is shown that the problem can be treated systematically by means of asymptotic expansions and successive integration. The classic al laminated shell (CST) equations are derived as the leading-order ap proximation to the three-dimensional theory. The higher order correcti ons are determined by solving the CST equations in a consistent and hi erarchic manner. Illustrative examples are given to demonstrate the pe rformance of the theory.
