Damage Detection in Plates with the Use of Laser-Measured Mode Shapes

Figure 11

Results of damage detection for the first three modes, for a laboratory experiment, (a) MF method, (b) LMF method, and (c) WV method. Coloring of areas refers to damage scenarios under investigation, with temperature rise marked in dark grey and damage cases 1, 2, and 3 marked with light red, light yellow, and dark yellow, respectively. Values are normalized so each time maximum indication of the given method would equal 1.
