Calibrating data for isotropic elastic material behavior

The isotropic elastic calibration behavior enables you to derive isotropic elastic data (Young's modulus and Poisson's ratio) from calibration data sets and to apply these material constants to the elastic material properties of a material definition in your model.

  1. From the Model Tree, expand the Calibrations container and double-click Behaviors.

    The Create Calibration Behavior dialog box appears.

  2. Enter a name for the material calibration behavior, select Elastic Isotropic, and click Continue.

    The Edit Behavior dialog box appears.

  3. From the Parameter Set 1 options, do the following to calculate a value for Young's modulus:

    1. From the Data set list, select the data from which you want to calculate Young's modulus.
    2. Click .

      Abaqus/CAE computes Young's modulus and displays its value to the right of the Young's modulus label.

  4. From the Parameter Set 2 options, do the following to calculate a value for Poisson's ratio:

    1. From the Data set list, select the data from which you want to calculate Poisson's ratio.
    2. Click .

      Abaqus/CAE computes Poisson's ratio and displays its value to the right of the Poisson's ratio label.

  5. From the Material list, select the material definition to which you want to apply this calibration behavior; or click to create a new material definition for this calibration behavior. For more information about defining a new material model, see Creating or editing a material.

  6. Click OK to save the isotropic elastic behaviors to the selected material model.

    Abaqus/CAE adds the new behavior to the model tree and adds the specified Young's modulus and Poisson's ratio to the Elastic material properties for the specified material.
