Uniaxial high-temperature creep property predictions made by CDM and MPC omega techniques for ASME SA 455 steel

The objective of this work was to determine if the Kachanov one-state variable continuum damage mechanics technique and the MPC omega method could accurately model SA 455 steel’s high-temperature creep behaviour.The steps required for extracting needed material constants from the creep rupture experimental data were presented. Uniaxial finite element analyses were performed using the material constants found for each of the two creep damage …
