Damage stabilization

This option is used to specify viscosity coefficients used in the viscous regularization scheme for the damage model for traction separation laws and fiber-reinforced materials. Viscous regularization is intended to improve convergence as the material fails.

The following topics are discussed:

Defining damage stabilization for traction separation laws

Damage stabilization is available for use with the following damage models for traction separation laws:

You define damage stabilization for traction separation laws by entering the viscosity coefficient.

Defining damage stabilization for fiber-reinforced materials

Damage stabilization is available for use with the following damage model for fiber-reinforced materials:

  • Hashin damage model. (For information on entering the Hashin damage initiation criterion in Abaqus/CAE, see Hashin damage.”)

For more information, see Viscous regularization.

You define damage stabilization for fiber-reinforced materials by entering viscosity coefficients for each of the potential failure modes:

  • Fiber tensile failure

  • Fiber compressive failure

  • Matrix tensile failure

  • Matrix compressive failure

Each of the viscous coefficients should be small compared to the increment size.
