Abstract
The invention relates to an assembly for nondestructive material testing with which shear waves are emitted and detected in elastic surfaces of components or workpieces, in which piezoelectric transducer elements are arranged above one another in multiple planes and the piezoelectric transducer elements arranged in adjacent planes can each be operated oppositely to one another. The piezoelectric transducer elements can be piezoelectric fibers and/or piezoelectric plate-like elements that are connected to or embedded in an elastically deformable material.
