NONLINEAR VIBRATION CHARACTERISTICS OF A CANTILEVER BEAM WITH A BREATHING CRACK BASED ON VIBRATION POWER FLOW
Crack is one common damage in key cantilever beam structures and early crack identification is much significant for increasing safety and reducing accidents. However, classical methods based on displacements are less sensitive to small cracks. By introducing the concept of vibration power flow analy...
