Hashin damage

From the menu bar in the Edit Material dialog box, select Mechanical Damage for Fiber-Reinforced Composites Hashin Damage .

(For information on displaying the Edit Material dialog box, see Creating or editing a material.)

Select

α = 0

to use the model proposed in 1973 and

α = 1

to use the 1980 model. (For more information, see Damage Initiation for Fiber-Reinforced Composites.)

To define material damage data that depend on temperature, toggle on Use temperature-dependent data.

A column labeled Temp appears in the Data table.

To define behavior data that depend on field variables, click the arrows to the right of the Number of field variables field to increase or decrease the number of field variables.

Field variable columns appear in the Data table.

Enter damage parameters in the Data table:

Longitudinal Tensile Strength: Longitudinal tensile strength.
Longitudinal Compressive Strength: Longitudinal compressive strength.
Transverse Tensile Strength: Transverse tensile strength.
Transverse Compressive Strength: Transverse compressive strength.
Longitudinal Shear Strength: Longitudinal shear strength.
Transverse Shear Strength: Transverse shear strength.
Temp: Temperature, $θ$ .
Field n: Predefined field variables.

You might need to expand the dialog box to see all the columns in the Data table. For detailed information on how to enter data, see Entering tabular data.

Select Suboptions Damage Evolution to define the material degradation that takes place once damage begins.

For more information, see Damage evolution.”

Select Suboptions Damage Stabilization to enter viscous coefficients and improve the model convergence.

For more information, see Damage stabilization.”
