Improved Complex-valued Radial Basis Function (ICRBF) neural networks on multiple crack identification
A two-stage ICRBF neural network is developed for multiple crack identification. Conventional CRBF neural network is used in the first stage of ICRBF. Reduced search space moving technique is used in the second stage of ICRBF. Crack location and depth are identified using frequency domain vibration signals. ICRBF is more efficient followed by IRBF, CRBF, RBF and MLP neural networks.
