Visualization of wave modes generated by electromagnetic acoustic transducers with the photoelastic imager
Published 2023-08-01“…By generating waves in conductive but non-magnetic, non-conductive but magnetic and conductive and magnetic materials the contributions of Lorenz-, magnetic and magnetostrictive forces could be separated. It is found that transversal waves have their origin in Lorenz- and magnetostrictive forces, while the largest contribution to longitudinal waves comes from magnetic forces leading to an unfavourable propagation direction. …”
