Modal Vibration Analysis

Cracks in vibrating component can initiate catastrophic failures. The presence of crack results in change in the physical characteristics of a structure which in turn alter its dynamic response characteristics. Therefore, it is necessary to understand dynamics of structures when it is subjected to defect like a crack. Crack depth and location are the main parameters for the vibration analysis. So, it is necessary to develop analytical and experimental method to obtain dynamic response characteristics for different parameters like crack depth and crack location which can be used to find the effect of these parameters on the dynamic response characteristics. Results of analytical and experimental method can be used to access the structural integrity, performance and safety of structure. In the present study, vibration analysis of cantilever beam with single open transverse crack with different crack depth and different crack locations, under no load and transverse load condition is carried out
