Cracks, masses, vibrations, elastic constraints, detection, induced errorAbstract
This work analyzes an analytical method for detecting multiple cracks in beams with differents elastics constraints by inducing an error in the frequency coefficients, which are input data to the method, to assess its robustness. The method uses a point masses to induce favorable effects on crack detection. The mathematical model consists on point masses and general elsatic conditions at their ends and intermediate points, which allow modeling different crack positions and depths. The Ritz method is used to obtain numerical results.
