摘要
The effect of compressive stress on linearized coefficients for ferroelectric ceramics has been extensively reported experimentally. However, there is no proper model for this effect which could be pertinent to designers of force sensors. This paper introduces a model based on a ferroelectric multiscale model in order to predict the effect of compressive stress on the piezoelectric constitutive laws. The comparison with experimental data shows an excellent qualitative agreement and the use of this model gives new insights on this nonlinear and hysteretic effect.
