From the Bonding tabbed page, toggle on Limit bonding to slave nodes in subset, and choose the set that specifies the initially bonded nodes of the slave surface.

Select a discretization method of Surface to surface.

Specify the critical energy release rates for crack onset and propagation.Ĭreate a surface-to-surface contact interaction that specifies the master and slave surfaces (the region that contains the potential crack surfaces), as described in Defining surface-to-surface contact in an Abaqus/Standard analysis.

The Direction of crack growth relative to 1–direction option applies only to enriched regions that will be used by the extended finite element method ( XFEM) for crack propagation.

Choose the crack propagation criteria ( VCCT or Enhanced VCCT).

The virtual crack closure technique cannot model crack initiation from a surface that is not already cracked therefore, you must specify a clearance between the slave and master surfaces that models a preexisting flaw at the beginning of the crack surface.įor more information, see Crack propagation analysis.Ĭreate a contact interaction property that defines the mechanical fracture criterion, as described in Specifying fracture criterion properties for crack propagation.

The crack continues to propagate along the interface between the master and slave surfaces. For detailed information, see Defining initially bonded crack surfaces in Abaqus/Standard.Īctivate the crack propagation capability to specify that crack propagation can occur between the two surfaces that are initially partially bonded. The unbonded portion of the slave surface behaves as a regular contact surface. The initially bonded region defines a region of the slave surface that is initially bonded with the master surface. For more information, see Enhanced VCCT criterion.Ĭreate a surface-to-surface contact interaction that models the potential crack surfaces using master and slave contact surfaces. The enhanced virtual crack closure technique is available only in an Abaqus/Standard analysis. The enhanced virtual crack closure technique ( Enhanced VCCT) criterion, in which you can control the onset and growth of a crack using two different critical fracture energy release rates. For more information, see VCCT criterion. The virtual crack closure technique ( VCCT) criterion, which uses the principles of linear elastic fracture mechanics. You can choose between the following crack propagation criteria: The fracture criterion interaction property specifies the criterion for crack propagation along initially partially bonded surfaces. You can create a virtual crack closure technique ( VCCT) crack that can be analyzed by Abaqus/Standard by doing the following:Ĭreate a contact interaction property that specifies the fracture criterion.
