A model for heat generation by acoustic waves in piezoelectric materials: Global large-data solutions
Leander Claes, Johannes Lankeit, Michael Winkler
A model for the generation of heat due to mechanical losses during acoustic wave propagation in a solid is considered in a Kelvin-Voigt type framework. In contrast to previous stud…

Estimation of acoustic wave non-linearity in ultrasonic measurement systems
Leander Claes, Carolin Steidl, Tim Hetkämper +1
Most measurement methods based on ultrasound, such as sound velocity, absorption or flow measurement systems, require that the acoustic wave propagation is linear. In many cases, l…
