This paper describes theoretical treatment of problems of thermal stress and thermal bending due to partially distributed heat supply for a multilayered anisotropic laminated plate. As an analytical model, we consider a laminated rectangular plate consisting of a diagonal stack of layers having orthotropic material properties, i. e. an angle-ply laminate. Introducing the Rayleigh-Ritz method based on the variational principle, a three-dimensional temperature solution for a transient state is given. Moreover, for the thermoelastic problems, the components of displacements are analyzed using the Rayleigh-Ritz method, and the characteristic behaviors of thermal stress and thermal deformation for a simply supported plate are determined. As an example, calculations are carried out for a 2-layered angle-ply laminate, and the results are examined precisely.
