Damage Orientation Method Based on the Modal Kinetic Energy

Abstract:

Dynamic methods by structural vibration responses and system dynamic characteristic parameters are the main methods for structural damage identification. Based on the modal strain energy method and used unit location matrix instead of element mass matrix, modal kinetic method is proposed. Two kinds of typical damage condition were simulated and the results show that the method can reduce structural finite element model accuracy, calculate simply and realize the initial damage location.
