Finding Damage Localizations of a Planar Truss Using Modal Strain Energy Change

Figure 3

Mode shapes of the first ten modes of the planar truss (the thin dashed lines represent the equilibrium configuration, while the thick solid lines denote modal displacements enlarged by 2 times): (a) mode 1, (b) mode 2, (c) mode 3, (d) mode 4, (e) mode 5, (f) mode 6, (g) mode 7, (h) mode 8, (i) mode 9, and (j) mode 10.
