CONSTRUCTION OF THE COMBINED ALGORITHM OF BILATERAL ESTIMATIONS OF DIFFERENT-MODULUS BODIES` STRAIN ENERGY

The combined algorithm based on two well-known duality algorithms – the method of refreezing of differential connections and the method of hypercircle is introduced. The applications of this algorithm to both linear and physical nonlinear elastic boundary-value problems are examined. The results of numerical experiments are given.

Keywords: duality, variational principle, different-modulus body, refreezing of differential connections, hypercircle.
