title = "Damage detection in plate structures using modal power flow analysis",
abstract = "The power flow and energy distribution of a vibration mode of a damaged plate is studied experimentally. Variation of the modal reactive power distribution of a damaged plate is experimentally evaluated with a scanning LDV and compared to the theoretical predictions. Large variation of local reactive power flow in or around the damage region of a plate under resonant vibration is found to be related to the change of strain and kinetic energies in the damage region. Feasibility of damage identification based on the detection of this local variation of modal reactive power flow in a structure is studied.",
