Description

(1) Experimental measurements of the spatial distribution of zero-group-velocity Lamb mode resonance frequency as a function of loading cycles during the whole fatigue lifetime (fatigue loading in a two sides clamped compression configuration inducing buckling). (2) Examples of numerical calculations, to perform frequency-wavenumber (f-k) analyzes of the Lamb modes in a fatigued sample (Aluminum) realized using the finite element method, for both intact (loading cycles = 0) and damaged (loading cycles = 4000, 9500 and 10000) cases.
