5.11 shear wave; rotational wave. Wave in an elastic medium which causes an element of the medium to change its shape without a change in volume.
Annotation 1 Mathematically, a shear wave is one for which the velocity field has zero divergence.
Annotation 2 A shear wave in an isotropic medium is a transverse wave.
Annotation 3 When shear waves combine to produce standing waves, linear displacements may result.« Back to Standards Terminolgy Index
