In SHM, Lamb wave is a frequently used term. Lamb wave is named for Horace Lamb (1849-1934, a British scientist) in honor of his fundamental contributions to this subject. It is a type of ultrasonic wave propagating between two parallel surfaces of a structure. Lamb wave can propagate in symmetrical or anti-symmetrical modes. The velocity of Lamb wave depends primarily on the product of actuation frequency and the thickness of the structure.
