US 2021/0041399 A1: Arrangement For Non-Destructive Testing And A Testing Method Thereof (2022)
Abstract: An arrangement for non-destructive testing of a component part, which may include a first end surface and a second opposite end surface. The arrangement may include a plurality of discrete piezoelectric transduction elements arranged in a circular array on the first end surface, and an electric wave signal transmitting and receiving unit electrically coupled to the piezoelectric transduction elements. The electric wave signal transmitting and receiving unit may be able to generate an electric excitation wave signal and to receive an electric response wave signal. The piezoelectric transduction elements may deform, upon an application of the electric excitation wave signal, in an in-phase shearing motion parallel to the first end surface and in respective tangential direction with respect to the circular array so as to generate a corresponding structure-borne wave in the component part at the first end surface such that said structure-borne wave can propagate in the component part.
