Abstract: Due to the large coupling between their electrical and mechanical properties, as an important functional material, ferroelectric ceramics has been used successfully in many fields. The nonlinear constitutive behavior of ferroelectric ceramics is one of the important frontiers and hotspots in recent research of solid mechanical and material science. Typical characteristics of the nonlinear constitutive behavior of ferroelectric ceramics and its microphysical mechanism were introduced in this paper firstly. Then the experimental progress in the nonlinear constitutive behavior of ferroelectric ceramics is reviewed in detail. In addition new development trends of nonlinear constitutive experiment of ferroelectric ceramics were introduced.
