Damage Detection Using Finite Element Model Updating
Journal of Ocean Engineering and Technology, 2012 In this study, a damage detection method that uses sensitivity-based finite (FE) element model updating with the natural frequency and zero frequency was proposed. The stiffness matrix for a structure was modified using the sensitivity-based FE model updating method.
