Study for multilayer piezoelectric composite structure as displacement actuator by Moire interferometry and infrared thermography experiments

Qiu, Wei; Kang, Yi Lan; Qin, Qing Hua; Sun, Qing-Chi; Xu, Fang-Yu


Multilayer piezoelectric structures are widely applied as a smart structure in precise apparatus. When the structure is in service, fractures often occur near the internal electrode layers. To analyze this issue, a multilayer piezoceramic structure used as displacement actuator is investigated both experimentally and numerically in this paper. Through Moiré interferometry experiment, the plane displacement distribution of the structure is obtained, which is holistically consistent with and...[Show more]
