Crack Detection of Fixed-Simply Supported Euler Bernoulli Beam Using Elman Networks

Abstract In this paper, the crack detection and depth ratio estimation method are presented in beamlike structures using Elman Networks. For this purpose, by using the frequencies of modes as input, crack depth ratio of each element was detected as output. Performance of the proposed method was evaluated by using three numerical scenarios of crack for fixed-simply supported beam consisting of a single cracked, two cracked and three cracked beams have been investigated. The results indicate that the proposed method is effective in the crack detection and estimation of crack depth ratio in beam-like structures.
