*SUPERELASTIC

Define the data for the superelastic model.

This option is used to define the data for the superelastic material model. It can be used only in conjunction with the ELASTIC option.

Optional parameters

NON ASSOCIATED
Set this parameter equal to the volumetric transformation strain, εVL. If this parameter is omitted, the volumetric transformation strain is assumed to be equal to the uniaxial transformation strain, εL.
SHAPE SET FIELD
Set this parameter equal to the user-defined field variable number that will drive the shape setting process.

Data lines to define the superelastic model

First line

  1. Young's modulus of martensite, EM.

  2. Poisson's ratio of martensite, νM.

  3. Uniaxial transformation strain, εL.

  4. Stress at which the transformation begins during loading in tension, σtLS.

  5. Stress at which the transformation ends during loading in tension, σtLE.

  6. Stress at which the reverse transformation begins during unloading in tension, σtUS.

  7. Stress at which the reverse transformation ends during unloading in tension, σtUE.

  8. Stress at which the transformation begins during loading in compression, as a positive value, σcLS.

Second line

  1. Reference temperature, T0.

  2. Slope of the stress versus temperature curve for loading, (δσδT)L.

  3. Slope of the stress versus temperature curve for unloading, (δσδT)U.

  4. Value of the user-defined field variable at which the shape setting process will be triggered. It should be used in conjunction with the SHAPE SET FIELD parameter.
