压电陶瓷材料性能测试方法 泊松比σE的测试
Application Summary AI generated
This standard specifies the method for determining Poisson's ratio (σE) of piezoelectric ceramic materials under a constant electric field. It is applied in the electronics industry for quality control and material characterization of piezoelectric ceramics used in transducers, sensors, and actuators. The test involves measuring the resonant and anti-resonant frequencies of a specific sample geometry to calculate the elastic compliance constants.
