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