Hashin damage

From the menu bar in the Edit Material dialog box, select MechanicalDamage for Fiber-Reinforced CompositesHashin Damage.

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

Select $\alpha =0$ to use the model proposed in 1973 and $\alpha =1$ 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:

Fiber Tensile Strength

Fiber tensile strength.

Fiber Compressive Strength

Fiber compressive strength.

Matrix Tensile Strength

Matrix tensile strength.

Matrix Compressive Strength

Matrix compressive strength.

Longitudinal Shear Strength

Longitudinal shear strength.

Transverse Shear Strength

Transverse shear strength.

Temp

Temperature, $\theta$.

Field n

Predefined field variables.

You may 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 SuboptionsDamage Evolution to define the material degradation that takes place once damage begins.

For more information, see Damage evolution.”

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

For more information, see Damage stabilization.”
