摘要: This paper deals with the identification of a single crack in beam based on knowledge damage-induced variations static deflection beam. The is simulated by an equivalent linear spring connecting two adjacent segments Sufficient conditions measurements which allow for unique are presented and discussed. inverse analysis provides exact closed-form expressions position severity as functions different boundary conditions. theoretical results confirmed comparison steel beams crack. Extension to multiple cracks briefly
