Abstract

Implicit two-point differential-difference parallel iterative domain decomposition algorithms are proposed to solve the multibody contact problems of elasticity. A program implementation of these algorithms based on the finite element approximations is made for the case of plane contact problems. The influence of the iterative parameters on the convergence rate of presented algorithms is investigated. The numerical efficiency of different two-point and one-point iterative algorithms is compared.
