| Abstract: | Constant boundary contact problems in practical engineering often occur. It ismeaningful to precisely calculate stress and displacement in the contact area using an effec-tive method. A mixed finite element method for the contact problems with constant bound-ary by Hellinger-Reissner's general variation principle in two variates is studied and somenumerical examples are presented. These numerical results show that this proposed methodis effective. |
