Stress influence matrix on hot spot stress analysis for welded tubular joint in offshore jacket structure
The detailed finite element (DFE) simulation of welded offshore tubular joint can give realistic and sound hot-spot stress (HSS) estimates regarding fatigue design of jacket substructures for offshore wind turbines. However, the computational efforts and time costs due to complicated joint configurations and a large quantity of design load cases have prompted the design practitioners likely resort to a simple alternative, the SCF method, which is also rooted in the DFE simulation. The present study attempted to optimize the conventional DFE simulation procedure by applying a stress influence matrix (SIM) method and its modified version gSIM, along with discrete joint formulation techniques, to simplify and make efficient of the DFE process, and then incorporating point positioning techniques to eventually ease the HSS evaluation. Through an implementation case involving a KK tubular joint, the gSIM method proved its robustness, reliability and computationally efficiency in joint HSS evaluation practice.
