Full-Text - Abstract

NDT related quantitative modelling of coupled Piezoelectric and Ultrasonic Wave Phenomena Quantitative methods in Ultrasonic Non Destructive evaluation requires more and more deep and fundamental physical understanding of elastic wave propagation and scattering in solids and, consequently, numerical codes to model these phenomena.

Starting from a team work which laid the foundation for a numerical technique called EFIT (Elastodynamic Finite Integration Technique), R. Marklein has substantially further developed and applied this code. The latest scientific milestone comprises the inclusion of coupled piezoelectric and ultrasonic wave phenomena to account explicitly for the modelling of the transducer as a transformer of electrical quantities, i.e. voltage and current, into elastodynamic quantities i.e. displacement and stress.
