摘要：

An efficient crack propagation (CP) simulation system based on a shell-solid finite element (FE) modeling is newly established. Three-dimensional (3D) CP simulation for a curvilinearly propagating surface crack in a steel circular hollow section (CHS) T-joint is carried out. Entire model is generated by a shell FEs, and cracked welded part is generated by a solid FEs. They are connected with a rigid body element (RBE). Stress intensity factors (SIFs) are computed for analyzing CP rate and CP direction of the crack employing the virtual crack closure-integral method (VCCM) with quadratic tetrahedral FEs. When the crack extends, only solid model is regenerated. To examine the effectiveness of the modeling, fatigue testing and simplified CP simulation results are employed. Hot spot stress (HSS) and weld toe magnification factor (Mk factor) formulas are used for the simplified CP method. CP phenomena of the fatigue test are studied through the fatigue assessment methods.
