The interaction between contacting surfaces consists of two
components: one normal to the surfaces and one tangential to the surfaces.
The tangential component consists of the relative motion
(sliding) of the surfaces and, possibly, frictional shear stresses. Each
contact interaction can refer to a contact property that specifies a model for
the interaction between the contacting surfaces. There are several contact
interaction models available in
Abaqus;
the default model is frictionless contact with no bonding.
