A general technique for coupling two arbitrary methods in stress analysis. (English) Zbl 1359.74413

Summary: In this paper, a general technique for coupling two arbitrary methods is presented. The problem domain is decomposed into two sub-domains. Afterwards, a sensitivity analysis at the interface of each sub-domain is carried out. Sensitivity matrices of the two sub-domains are used to find the coupling matrix equation. Unknowns at the interface are then found by solving the equations. The size of the matrix equation is very small in comparison with coefficient matrices of each sub-domain. The present method allows the black box coupling of different methods, even commercial software without having access to the matrices created by the methods.
