Simulations And Measurement Of Acoustic Emission Effects

Abstract

This paper deals with issue of method of acoustic emission and performed measurements of acoustic emission signals and simulation of this phenomenon. Main interest is given into measurement of acoustic emission transducer displacement to verify homogeneity on its surface in time and simulations by finite element method. Performed simulations deal with displacement calculation of calibration block after a capillary break, calculation of impedance characteristics of piezoelectric sensing element and their comparison with analytic solution or measurement.
