A NUMERICAL STUDY REGARDING THE INFLUENCE OF THE LONGITUDINAL EXTENT OF A T-SHAPED CRACK ON THE EIGENFREQUENCY DECREASE OF CANTILEVER BEAMS

The paper analyzes the effects of T-shaped cracks in beams regarding the manner in which the frequencies of the bending modes change. We determined the eigenfrequencies of the damaged beam involving the finite element method for five lengths of the branched crack’s longitudinal components and numer...
