F. Ashida et al., A 2-DIMENSIONAL PIEZOTHERMOELASTIC PROBLEM IN AN ORTHOTROPIC PLATE EXHIBITING CRYSTAL CLASS MM2, JSME international journal. Series A, mechanics and material engineering, 37(4), 1994, pp. 334-340
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.
