Natural frequency can be defined as the frequency at which a system tends to vibrate after giving it an initial excitation. All the engineering structures are subjected to some static and dynamic loads with a certain frequency of vibration during their service. Resonance occurs in structures, when the frequency of vibration is equal to the natural frequency of the structures. Calculation of natural frequencies is made for fault diagnosis of structures. In the present work, comparison of natural frequencies of AISI 1018 mild steel cantilever beam through an analytical, modal test, numerical method (FEM), and programming software MATLAB are performed. It was found that there is a good agreement between the results and a maximum error is observed at first mode between the analytical and modal test results by 7.51%.
