Application of PVDF in dynamic strain measurement

LI Yan, ZHONG Fangping, LIU Qian, LIU Yu, QIN Xuejun, TAN Hongmei(Northwest Institute of Nuclear Technology, Xi'an 710024, Shaanxi, China)  
The principle and the method of dynamic strain measurement with PVDF piezoelectric film were investigated. The straincharge constants of two PVDF strain gauges were calibrated with a unidirectional strain block. The strain waves in a uniaxial stress bar were measured with these gauges. Experimental results of good precision were obtained.
