Abstract
Bender element is made of connecting two piezoelectric elements which have different polarities from each other, and is a kind of sensors which can be used either way as a source making elastic wave or a receiver. Elastic waves generated by stimulating the bender elements can be decomposed to P-wave and S-wave propagation. Numerical and expeimental studies are conducted, and results show that multiple measurements are recommended to determine wave arrivals from the received signals.
