Abstract: This paper deals with elastic contact problems of multibody, which belongto category of boundary condition nonlinearity with small deformation. Usingthe mixed approach of F.E.M, we have derived iteration formulations of thecontact problems and given a method of efficient computation. This method haspractical value for engineering design. Especially it can efficiently analyze complicated mechanical problems in metallurgical equipment such as elastic deformations for mill rolls and pressing plates of water press.
