Weighted residuals as a basis of a general solution method in elasticity. (English) Zbl 0536.73014
Summary: It is shown that the general integral form of the elastic equilibrium equations obtainable through the weighted residuals agrees with the variational formulation given by the extremum conditions of the Washizu functional allowing a complete relaxation of the interelement continuity requirements.
