Damage Detection in Double Layer Grids with Modal Strain Energy Method and Dempster-Shafer Theory [PDF]
Change in modal strain energy is one of the indicators used to detect damage in structures. However, in structures with high degrees of freedom, such as double-layer grids, this method requires a relatively large number of mode shapes which in practice ...

Non-reciprocal piezoelectric metamaterials with tunable mode shapes
The mode shapes of piezoelectric metamaterials are tuned by manipulating spatially the electrical boundary conditions of the piezo-elements, in a desired and controlled manner, in order to tailor the wave propagation characteristics through these ...

Crack detection of a beam-like bridge using 3D mode shapes
In this paper, mode shapes of a 3D cracked beam with a rectangular cross section are analyzed for crack detection. The influence of coupling mechanism between horizontal and vertical bending vibrations due to the 3D crack model on the mode shapes is ...
