of cracks in beams

ABSTRACT: This paper propose a method to assess damages in beams, based on the fact that frequency shifts
can be described mathematically using two terms, one defining damage location and one damage depth. It was
demonstrated that series of local values of mode shape curvature squares of several bending vibration modes
uniquely characterize ...
