The extended finite element method (XFEM) using a crack tip element (TIP element), which is enriched through only the Heaviside function, is applied to crack and its propagation analysis in two-dimensional elastic problems. In the proposed method,...
Purpose - The purpose of this paper is to investigate the effects of the finite element models on the response of a free surface or a floating roof, which is important for safety assessment of oil storage tanks.
Design/methodology/approach - Struc...
The extended finite element method is applied to stress analyses of composite laminates modeled by shell elements. In the proposed method, a thin-walled structure containing an interface is modeled by shell elements, and the nodes on the interface...
In order to evaluate fatigue crack propagation behavior at J-welding portions of Bottom Mounted Instrumentation (BMI) in Reactor Pressure Vessel (RPV), crack propagation crossing dissimilar material interface between base metal and clad should be ...
