【Abstract】 The dynamic governing equations for piezothermoelasticity continua are presented to discuss the effects of coupling fields on the control/sensing performance in an intelligent structure. According to those analyses, a finite element analysis method is developed to calculate the thermal stress and thermal deformation of piezothermoelectric basal structure in order to determine the piezoelectric actuator/sensor optimal placement in the intelligent structure.更多还原
