Damage Models

Critical Stretch

The critical value correspondends to the critical stretch for this model, defined in the theory manual.

Critical Energy

Interblock Damage

Interlaminar behaviour between different material blocks can be defined using the Interblock Critical Value parameter. If a Bond is crossing a block interface, a user defined critical damage value is applied to the bonds.

As bonds are bidirectional, the critical damage value can be defined for both orientations, for example:

• Interblock Damage:
  • Interblock Critical Value 1_2: 0.1
  • Interblock Critical Value 2_1: 0.1

Bonds that aren't crossing a block interface are not affected by the interblock damage model.
