Contact Constraints and Constitutive Equations for Contact Tractions
It is required to define the contact conditions including both geometrical conditions such as non-penetration and sticking, and constitutive relations for contact forces and stresses. With regards to the introduced coordinate system and kinematics the contact tractions are naturally split into normal and tangential components. If for the normal components non-penetration conditions can be formulated then for tangential components the constitutive relations are required.
