Abstract

A damage is one of the vital characteristics of the structural analysis because of safety cause as well as the economic prosperity of the industries. Identification of faults in dynamic structures and components are a significant aspect of judgment creating about their overhaul and retirement. The existence of cracks which influence the performance of structures as well as the vibrational parameters like modal natural frequencies, mode shapes, modal damping, and stiffness. In the present work, the effect of crack parameters (relative crack location and crack depth) on the vibrational parameters of a cracked cantilever beam are examined by different techniques using numerical method, finite element analysis (FEA), using ANSYS. Finite Element Method has been accomplished to derive the vibration signatures of the cracked cantilever beam. The results obtained analytically are validated with the results obtained from the FEA. The simulations of FEA have done with the help of ANSYS software. Similarly, the Modal analysis is carried out using ANSYS software. Harmonic analysis is done to observe the resonating and anti-resonating peaks for the Un-cracked and cracked cases considered. The stresses induced due to crack are obtained from the static structure analysis done with the help of ANSYS software. The natural frequencies values obtained from all these approaches are observed and the final conclusions are drawn. With the increase in crack depth, there is an increase in natural frequency. When the distance of crack from fixed end is increased there is an increase in natural frequency.
