| Abstract: | Experimental analysis of ferroelectric composites with a viscoelastic and dielectric relaxation matrix is carried out, and
the electromechanical coupling behavior of the ferroelectric composites is calculated by means of the constitutive model proposed
in this paper. Comparisons between the experimental results and the calculations show that the constitutive model can reflect
the electromechanical coupling behavior of the ferroelectric composites. The analysis indicates that the effect of viscoelasticity
and dielectric relaxation of the matrix on the electromechanical coupling behavior of ferroelectric composites cannot be neglected. |
