Peculiarities of excitation and propagation of the rayleigh wave in solids with radial transitions
The peculiarities of the elastic wave excitation and propagation with the usage of Rayleigh wave probes having the βR prism angle are presented. The paper shows the possibility in principle of using such probes for determining not only surface defects but also defects with low reflecting ability, located in the fillet. Dependences of the factor of conversion of the Raleigh wave into edge waves when the surface wave travels across the radial transition are obtained. It is revealed, how the «concurrent» transverse wave excited simultaneously with the fundamental mode influences the resulting field formed in the fillet.
