Ultrasonic backscattering techniques are useful for locating interlaminar cracks.
👉 When the limitation of front or far surface resolution is critical, avoiding specular reflection from the front and back test object surfaces can provide a substantial advantage.
👉 This approach has been effective for discontinuities in composites, for corrosion and for tests of aluminum laminate materials.
👉 The technique is based on the fact that discontinuities (fibers, corrosion, microcracks, porosity) scatter waves backward when the incident wave is normal to their surface.
