Vibration analysis of cracked cantilever beam boundery conditions.

      Аннотация: The objective is study of the behavior of Cantilever Beam with different boundary conditions, when they are faced to crack. The knowledge of natural frequencies of component is of great interest in the analysis of response of structures to various behaviors. This work will help the Engineers to know the Natural frequency changes and will give an idea for values of natural frequency for different crack depth and with different two transverse crack lengths. The presence of damage is typically confirmed by witnessing changes in the Frequency of the structure before and after damage. The application of vibration analysis techniques, or more specifically the change in natural frequencies, is also one tool that can be also used for damage detection.Physical Modal and computational modal has been prepared. Vibration analysis done by using FEA (ANSYS) and compared with Experimental work by using FFT.
