THERMOELASTIC ANALYSTS OF LAMINATED PLATES. 2: ANTISYMMETRIC CROSS-PLY AND ANGLE-PLY LAMINATES

Abstract

Thermal deformations and stress resultants in rectangular, antisymmetric cross-ply and angle-ply laminates are investigated. Exact solutions are obtained for the response of simply supported plates to general three-dimensional temperature variations. To illustrate the thermoelastic behavior, deflections are computed for fiber-reinforced laminates undergoing constant and linearly varying temperature fields. Thermal membrane-bending coupling is found to be significant when the total number of layers is small, but it rapidly becomes unimportant as the number of layers within a plate of a given thickness increases.
