Synopsis

The stress concentration factor (SCF) computation is a key element in the fatigue assessment of offshore tubular joints. Mesh sensitivity research is conducted to identify the optimum mesh controls needed to create an extensive FE model library to develop an AI prediction model for the SCF prediction. Nine finite element models with varying mesh controls are analysed for the mesh sensitivity study. The optimum mesh controls for the Finite Element Model for estimating the SCF of steel tubular joints were identified. A python code for an automated mesh generation for tubular T joints with identified mesh controls using APDL commands in ANSYS is developed.
