Abstract
In the first part of this paper, the influences of some of crack parameters on natural frequencies of a cracked cantilever Functionally Graded Beam (FGB) are studied. A cantilever beam is model ed using Finite Element Method (FEM) and its natural frequencies are obtained for different conditions of cracks.Then effect of variation of depth and location of cracks on natural frequencies of FGB with single and multiple cracks are investigated. In the second part, two Multi -Layer Feed Forward (MLFF) Artificial Neural Networks (ANNs) are designed for prediction of FGB's Cracks ’location and depth. Particle Swarm Optimization (PSO) and Back - Error Propagation (BEP) algorithms are applied for training ANN s. The accuracy of two training methods’ results are investigated
