Abstract :

Abstract Cracks in vibrating component can initiate catastrophic failures. The presences of cracks change the physical characteristics of a structure which in turn alter its dynamic response characteristics. Therefore there is need to understand dynamics of cracked structures. Crack depth and location are the main parameters for the vibration analysis. So it becomes very important to monitor the changes in the response parameters of the structure to access structural integrity, performance and safety. To examine the effect of the crack to the natural frequency of beams. Experiment Performed on aluminium beam with different crack location and crack depth.It is found that at first mode there is no appreciable variation in natural frequency.Impact height load is a significant parameter described in this paper. As impact load height increases, stresses also increases in cracked beam as compaired to uncracked beam. Ansys is used for simulation work. It is found that well match of Experimental,Numerical and FEM Results and the presence of crack changes the natural frequency of vibration. The mode shapes also changes considerably due to the presence of crack.
