    ANSYS Mechanical APDL - High Temperature Creep Modeling via Isochronous Curves

    ANSYS can be used to model creep in a number of different ways. If you are designing to ASME Section VIII, Div., 2 you might have to verify that your design meets the "shake down to elastic action" criteria. Basically, that means that the strains do not continue to increase over the number of...
