Description: You can use the virtual crack closure technique (VCCT) to study the initiation and propagation of a crack along a known crack surface. Abaqus/CAE supports modeling crack propagation using VCCT only for Abaqus/Standard models (three-dimensional solid and shell models and two-dimensional planar and axisymmetric models).

Interaction module: 
    SpecialCrackCreate: Name: crack name, Type: Debond using VCCT, select the step and
    the surface-to-surface (Standard) interaction, Debonding force: Step or Ramp
