The effect of damping and force application point on the non-linear dynamic behavior of a cracked beam at sub- and super-resonance vibrations
The finite element model of an elastic body with a closing crack is presented. Using this model, we show that the non-linear distortions of vibrations at superharmonic and subharmonic resonances are the high sensitive indicators of crack presence. The intensity of these indicators manifestation subs...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The finite element model of an elastic body with a closing crack is presented. Using this model, we show that the non-linear distortions of vibrations at superharmonic and subharmonic resonances are the high sensitive indicators of crack presence. The intensity of these indicators manifestation substantially depends on the level of damping in the system and on the load application point. |
