Vibration Analysis of Cracked Overhang Beam Using Experimental Method
The presence of cracks may winds up in damage in structural elements which ends up in in failure of the structure. So that the physical characteristics and dynamic response of a structure also changes. Hence it’s vital to check the dynamics of the structures within the current study; vibration analysis of an overhang beam with single open transverse crack for various crack depth and different crack locations is completed using experimental method. To research the vibration characteristics of overhang beam two cases are considered, first is without crack and second case is with crack. For transverse load condition an impact hammer is taken and impacted on five different points at same distance from fixed end of overhang beam from certain height. This analysis is completed to check the response characteristics (i.e. frequency and amplitude) of cracked overhang beam and to search out an effect of crack on these response characteristics. From the results, it’s found that, as crack depth increases natural frequency decreases.
