Abstract

This paper concerns the calculation of the unilateral contact forces and displacements between circular cylindrical shells and the saddles. The method of this computation depends on the formulation of a linear complementarity problem (LCP) or quadratic programming problem (QPP) which was derived from the numerical computation of the behavior of elastic bodies using Sanders' theory of shells subjected to unilateral contact boundary conditions that was governed by variational inequalities. This LCP is a direct extension of the force method of structural analysis. Solving such structural systems leads to the computation of the interface distribution stresses.
