Get PriceGuided waves offer the advantage of large-area inspection with a minimum number of installed sensors. In recent year, a large number of papers have been published on the use of Lamb waves for NDE and damage detection [13]. The advantages of Lamb and Rayleigh waves over P-waves for NDE applications were recognized in the early 1960s [1,8,14,15].
