Modification of the algorithm for calculating structurally nonlinear systems with one-sided connections by the finite element method in classical mixed form

Abstract

The problem of calculating systems with one-sided connections is a rather complicated one and a lot of attention and interest has been paid to it. The theory of calculating structures with one-sided elastic and inelastic bonds is connected with general problems of calculating beams, frames, plates contacting with one-sided bases of different types, with calculating span structures, bridges, tunnels and underground structures.
