A Two-Dimensional Thermoelasticity Solution for Bimodular Material Beams under the Combination Action of Thermal and Mechanical Loads

A typical characteristic of bimodular material beams is that when bending, the neutral layer beam does not coincide with its geometric middle surface since mechanical properties materials in tension and compression are different. In classical theory elasticity, however, this has been considered. study, a simply-supported under combination action thermal loads theoretically analyzed. First, simplified model concerning established. Based on model, Duhamel’s theorem used to transform thermoelastical problem into pure elasticity imaginary body force force. solving governing equation expressed terms displacement, special solution displacement found first, then by utilizing stress function method based subarea compression, supplement for without effect derived. Lastly, superimposed satisfy boundary conditions, thus obtaining two-dimensional thermoelasticity solution. addition, temperature illustrated computational examples.
