Study on dynamic properties of 1–3 cement-based piezoelectric composites
Highlights Under the same load, the potential shift increases with the increase of strain rate. The amplitude of potential shift decreases with the increase of loading times. PZT5H have good electromechanical response under load. 1–3 cement based piezoelectric composites have electromechanical response under load.
Abstract In this paper, Hopkinson compression bar technology is used to test the related properties of 1–3 cement-based piezoelectric composites under dynamic load. The research results prove that the stress and electric displacement of 1–3 cement-based piezoelectric composites have similar changing trends under dynamic action, that is, the response state of mechanical and electrical properties of the specimens is good. At the same time, due to the action of force, the phenomenon of electrical domain deflection and depolarization occurs, and the piezoelectric properties of the material also weaken with the increase of the number of loading.
