SUMMARYThis paper addresses the problem of thermo-elastic deflection in beams using a two-dimensional finite element idealization of the cross-section. Bending effects are introduced in a generalized plane strain formulation assuming that constant curvature dominates the flexural deformation. The method leads to a plane strain calculation which is very interesting from the computational point of view; thermal dependence of the physical properties can be taken into account, which would be inconceivable in a three-dimensional problem.
