Abstract: This paper presents a numerical methodology for three-dimensional crack propagation analysis based on remeshing. A crack tip opening displacement (CTOD) calculation method employing radial basis function (RBF) interpolation is proposed, and a critical CTOD criterion for crack propagation is established through a combined experimental and computational approach. The accuracy of the RBF-based CTOD calculation method is validated. Furthermore, a mesh deformation mapping strategy based on local RBF interpolation is developed, and quasi-static tensile fracture experiments and corresponding numerical simulations are conducted on stiffened panels containing cracks. Comparative analysis of experimental and simulation results demonstrates the feasibility of the proposed mesh deformation mapping strategy and elucidates the fracture mechanism governing crack propagation through the stiffener.
