Scattering of S0 Lamb mode in plate with multiple damage
چکیده انگلیسی

A study of scattering properties of S0 mode Lamb wave in an infinite plate with multiple damage is presented. Plate theory and wave function expansion method are used to derive the analytical solutions for the scattering wave field in plate with a single damage, and by using the addition theorems of Bessel functions, interference phenomena between scattering wave fields from different damage is investigated. Measurements agree well between theoretical results and FE simulation study of plate with two damage and validity of the model is confirmed. Numerical results of scattering displacement field in plate with two and three damage are graphically presented and discussed. An assessment of effects of damage geometric properties on the scattering properties is made.
