Description
This imperfect interface contact law implements an imperfect interface with tractions that depend on displacement discontinuities at the interface. It is currently the same as the Linear Imperfect Interface except the implementation is done differently. It is more approximate, but likely very close to linear law and possibly faster. In the future, this law (or subclasses of this law) will add actual non-linear traction laws.
Properties
The properties for this law are:
| Property | Description | Units | Default |
|---|---|---|---|
| Dnt (or Dn), Dnc, and Dt | See Linear Imperfect interface properties | pressure/length units | -1 |
| order | Specify order of approximation to interface laws as zeroth (0) or first (1) order | none | 1 |
