Evaluating the Thermal-Mechanical Response and Fatigue Life of Different Coke Drum Support Skirt Designs
In this article, the thermal-mechanical behaviors of multiple coke drum skirt designs, including forged, welded, and sliding configurations, are investigated using elastic and elastic-plastic finite element analysis (FEA), and corresponding fatigue life predictions are discussed for each type of design. Additionally, the effect of skirt slots is quantified. Finally, a cyclic plasticity material model is employed to establish shakedown, and a modern strain-based fatigue method is implemented, including a critical-plane approach. These results are compared to more conventional base metal and welded fatigue predictions.
