A 2-DIMENSIONAL PIEZOTHERMOELASTIC PROBLEM IN AN ORTHOTROPIC PLATE EXHIBITING CRYSTAL CLASS MM2

In the beginning of paper, a solution technique for two-dimensional pi ezothermoelastic problems in orthotropic solids of crystal class mm2 i s proposed. The solution technique is formulated in terms of two piezo thermoelastic potential functions, three piezoelastic potential functi ons and a single piezoelectric potential function. Next, by using the solution technique, a two-dimensional piezothermoelastic problem in an orthotropic thin plate of crystal class mm2 which is subjected to hea ting on one surface and electric surface charge on both surfaces is an alyzed. The numerical calculations are carried out for cadmium selenid e exhibiting class mm2 symmetry. The elastic displacements and stresse s are compared with those obtained for a similar thermoelastic problem without the piezoeffect. The effects of the electric surface charge o n the elastic displacements, stresses, electric potential, electric fi eld intensities and electric displacements are also investigated.
