摘      要：In this paper,the electroelastic stress fields in an electrostrictive material with point charge are ***,the general solutions for the potential functions of electric fields and stresses are derived for the case of point charge based on analytical continuation *** explicit results are given for the case of whole infinite *** the effect of interaction for the point charge and the perturbation or extra electric fields is *** is found that the stress functions are different from the ones of piezoelectric *** nonlinear effects for the coupling of electric and stress fields should be considered.
