The dynamics and diagnostics of cracked rotor have been gaining importance in recent years. Relatively few authors have addressed the problem of multi crack assessment for rotors. In the present study a modelbased method is proposed for the on-line identification of two cracks in a rotor. The fault-
A new method is proposed to detect and locate a crack in a rotor system. A vector quantity ''residue'' is defined using the measured vibration response of the rotor system and the modeled system matrices. It is shown that the non-zero elements of ''residue'' correspond to the nodes encompassing the
## Abstract Grouting is often considered to reinstate water tightness and displacement continuity in cracked concrete dams. Grouting alters the state of stress, deformation, and the strength of a dam in many ways. The state of stress prior to grouting is altered by the injection pressure that often
