The tool is an ANSYS APDL based script able to generate material properties characteristics, in SI units, for all the different materials (irradiated and unirradiated) contained in "SDC-IC In-vessel Components, Appendix A, Materials Design Limit Data, ITER_D_222RLN v3.2"
Definition of properties for the material model according "SDC-IC In-vessel Components, Appendix A".
Definition of other properties according "SDC-IC In-vessel Components, Appendix A".
- Definition of properties for the material model:
The properties for the material model are included in the material model that ANSYS use to describe the behavior of the material. These are:
• ALPX- Mean average or secant coefficient of thermal expansion
• CTEX- Instantaneous coefficient of thermal expansion
• EX- Young Modulus
• PRXY- Poisson's ratio
• DENS- Mass density
• KXX- Conductivity
• C- Specific heat
• MELAS- Stress-strain elastic curves. Nonlinear structural, multilinear elastic.
• BISO- Isotropic hardening plasticity. Bilinear stress-strain curves.
• MISO- Isotropic hardening plasticity. Multilinear stress-strain curves.
• BKIN- Kinematic hardening plasticity. Bilinear stress-strain curves.
• KINH- Kinematic hardening plasticity. Multilinear stress-strain curves.
- Definition of other properties:
The so called “other” properties are properties not included in the material model but which may be used for post-processing tasks. These are:
• SY_MIN - Minimum yield strength
• SY_AV - Average yield strength
• SU_MIN - Minimum tensile strength
• SU_AV - Average tensile strength
• SY_IRR_MIN - Minimum yield strength. Material irradiated

• STRAIN_RUPT_AV - Average true strain at rupture
• SM - Allowable stress intensity
• SMB - Design stress intensity for bolt materials
• SE_IRR - Allowable stress for the primary plus secondary membrane stress intensity dependent on temperature and neutron fluence.
• FATIGUE_STRAIN - Fatigue curves for unirradiated material. Number of cycles - Strain amplitude (Strain/2).
• FATIGUE_STRESS - Fatigue curves for unirradiated material. Number of cycles - Stress amplitude (Stress/2).
• K_CYCL - Coefficient for cyclic stress - strain curves
