An improved surface-to-surface bonding algorithm enforces bonding
interactions for faces that are not facing each other and have no projection area
between them.
A pair of faces qualifies for
bonding if these
conditions apply:
- The angle between the faces is less than a threshold value.
If
the angle between the faces exceeds the threshold value, the pair of faces
does not qualify for bonding.
- At least one face of the pair is a flat face (selected as Set 1 or Set
2 in the Local Interactions
PropertyManager).
The solver considers the flat face as the
target face to enforce bonding. The source face can be either flat or
curved.
The enhanced bonding algorithm applies to the surface-to-surface formulation and is
available for bonded interaction sets that you define using the
Local Interactions PropertyManager. It applies to these
studies: linear static, frequency, buckling, linear dynamic studies, and also fatigue
and design studies associated with linear static studies.
