![]() on the free and forced vibration of inhomogeneous Euler-Bernoulli beams containing open edge cracks. ![]() Studies based on structural health monitoring for crack detection deal with change in natural frequencies and mode shapes of the beam.Īn analytical study has been performed by Yang et al. As stated, beam type structures are being commonly used in steel construction and machinery industries. Considering the crack as a significant form of such damage, its modeling is an important step in studying the behavior of damaged structures. Cracks may develop in beam-like structures due to such loads. Introductionīeams are one of the most commonly used structural elements in numerous engineering applications and experience a wide variety of static and dynamic loads. The results of the proposed method are in good agreement with the results obtained from the developed experimental setup. The method proposed in the current analysis is used to evaluate the dynamic response of cracked cantilever beam. ![]() Relative crack locations and relative crack depths are the output parameters from the fuzzy inference system. The vibration parameters derived from the numerical methods of the cracked cantilever beam are used to set several fuzzy rules for designing the fuzzy controller used to predict the crack location and depth. This paper discusses the multicrack detection of structure using fuzzy Gaussian technique.
