On the influence of unilateral bonds on the stability and oscillations of elastic rings

The paper deals with the issues of stability of a circular ring compressed by uniformly distributed central forces in the presence of one-sided restrictions on displacements. In the second part of the article, the problem of oscillations of a ring supported by single-acting threads is solved. The problems are reduced to solving some variational problem under restrictions on the desired functions in the form of linear equations and inequalities
