Single element normal incidence Shear Wave Transducers contact transducers introduce shear waves directly into the test piece without the use of refracted wave mode conversion.
We recommend the use of our SWC shear wave couplant for general purpose testing.
概覽
Advantages:

• Generate shear waves which propagate perpendicular to the test surface
• For ease of alignment, the direction of the polarization of shear wave is nominally in line with the right angle connector
• The ratio of the longitudinal to shear wave components is generally below -30 dB

Applications:

• Shear wave velocity measurements
• Calculation of Young's Modulus of elasticity and shear modulus (see Technical Notes, page 46)
• Characterization of material grain structure
