- laser shock adhesion test
A nondestructive test, also referred to as LASAT, that uses a high-energy laser pulse that is targeted on an adhesively bonded part, resulting in the formation of plasma on its surface and, consequently, a pressure on the material surface due to the plasma expansion. This pressure produces a shock wave that will become release or tension waves after reflection on the sample’s back face. This tension wave will proof test the adhesive bond. There is a correlation between the laser energy and the tensile stress, which provides insights into the bonding quality.
