Interaction of debonded surfaces

This section outlines briefly how initially bonded surfaces may interact once they have started to debond. Details on defining a crack propagation analysis can be found in Crack propagation analysis.

When two initially bonded surfaces start to debond:

  • the debonded slave surface nodes are released and can move freely;

  • the tractions acting on the slave surface nodes at the instant of debonding are ramped down to zero using a user-supplied amplitude curve; and

  • the contact property models assigned to the contact pair formed by the two surfaces start to govern the interaction of the surfaces.
