ContactMaterial3D
This command is used to construct a ContactMaterial3D nDMaterial object.
nDMaterial ContactMaterial3D $matTag $mu $G $c
$t
matTag
|
unique integer tag identifying nDMaterial object |
mu
|
interface frictional coefficient |
G
|
interface stiffness parameter |
c
|
interface cohesive intercept |
t
|
interface tensile strength |
The ContactMaterial3D nDMaterial defines the constitutive behavior of a frictional interface between two bodies in contact. The interface defined by this material object allows for sticking, frictional slip, and separation between the two bodies in a three-dimensional analysis. A regularized Coulomb frictional law is assumed. Information on the theory behind this material can be found in, e.g. Wriggers (2002).
NOTE:
- The ContactMaterial3D nDMaterial has been written to work with the SimpleContact3D and BeamContact3D element objects.
- There are no valid recorder queries for this material other than those which are listed with those elements.
