Thermal Analysis of Laminated Composite and Sandwich Plates Using Layerwise Finite Element
Abstract
In this paper the quasi static response of laminated composite and sandwich plates subjected to lineary
varaying through the thickness and sinusoidall distributed in plane temperature field, is analyzed. Mathematical
model, based on layer-wise displacement field of Reddy [15], is formulated using small deflection linear-elasticity
theory. The principle of virtual displacements (PVD) is used to obtain the weak form of the mathematical model.
The weak form is discretized utilizing isoparametric finite element approximation. The originally coded MATLAB
program is used to investigate the influence of plate thickness on thermo-elastic response of laminate composite
and sandwich plates.
