“Ansys’ user programmable feature (UPF) was used to create a creep subroutine based on ASME code case 2605, which allowed us to evaluate the creep damage of pressure equipment at elevated temperatures in high strength chrome-moly steels.” Balram Kalra Assistant Manager-PED Design / ISGEC Hitachi Zosen Limited Ansys + ISGEC Hitachi Zosen Limited CASE STUDY /2 Ansys + ISGEC Hitachi Zosen Limited // CASE STUDY Creep damage contour plot after implementing the Ansys subroutine. Utilizing the Maximum Temperature Capability of Materials for Creep-Based Design of Pressure Equipment / Challen ges Code Case 2605 proposes carrying out full inelastic analysis, such as ratcheting elastic shakedown analysis, using the actual time-dependent thermal and mechanical loading histograms.
