title = "Quantitative detection of crack in structures based on finite element method of B-spline wavelet on the interval",
abstract = "The model-based forward and inverse problems in the diagnosis of structural crack fault were studied. The forward problem is to solve the natural frequencies through cracked structural model and the inverse problem is to quantitatively determine the crack parameters using the experimentally metrical frequencies. Then, The crack element of B-spline wavelet on the interval (BSWI) was built to solve the forward problem. Graphs of crack equivalent stiffness versus crack location were plotted by providing the first three natural frequencies as an input. The intersection of the three curves predicted the crack location and size. The numerical and experimental study verified the validity of the crack element in solving crack singular problems to overcome the disadvantages of traditional finite element method (FEM), such as low efficiency, insufficient accuracy, slow convergence to correct solutions etc. At the same time, it had adequate identification precision. The new method can be applied to prognosis and quantitative diagnosis of incipient cracks.",
