Comparative Study on the Modal Parameter of Cracked Beams
Crack occurrence is a crucial factor that affects the lifespan of civil structures. Cracks present on the surface of the structural element like beams, accounts changes in stiffness, flexibility and consequently their static and dynamic behaviour is affected. The influence of natural frequencies and modes of vibration of structures have been the subject of many investigations. The damage detection studies contain forward approach and inverse approach. The forward approach involves the determination of dynamic characteristics while inverse approach deals with detecting damage with the help of those characteristics. Forward approach is used in this study. The effect of crack location, crack depth, material and fixity conditions on the changes in natural frequencies of the beam are studied. The finite element analysis of different cases of cracked beam is done using the software Ansys Workbench and the results obtained are compared.
