Transient Thermal Stresses of Angle-Ply Laminated Strip due to Nonuiform Heat Supply in the Width Direction

Abstract

This paper is concerned with the theoretical treatment of transient thermal stress problem involving an angle-ply laminated strip consisting of an oblique pile of layers having orthotropic material properties due to nonuniform heat supply in the width direction. We obtain the exact solution for the two-dimensional temperature change in a transient state, and thermal stresses of a simple supported strip under the state of generalized plane deformation. As an example, numerical calculations are carried out for a 2-layered angle-ply laminated strip, and the numerical results for the temperature change, the displacement and the stress distributions are shown in figures. Furthermore, the influence of heat function on temperature change and thermal stress distributions are investigated.
