Investigations related to the determination of the oscillation parameters, depending on the type of defect largest section. Held Modal vibrations of a rod. Consider the form of vibrations and natural frequencies of finite element models of the cantilever with defects. Analysis of the resonance parameters shows that the largest deviation are as natural frequencies and vibration amplitude for a defect having unilateral execution. The calculation of the stress state bar loaded at the free end of the static force in the package Ansys.
