| Abstract: | The natural work principles with complementarity, energy principles with complemple-mentarity and variational inequalities for comtact problems and relations of those principles are investigated. The existence and uniqueness of the solution to the finite dimensional models are proved. Essential differences between the contact problems with friction and without friction and between two dimensional and three dimensional contact problems with friction are discussed. |
