What is it about?
We consider an elastic ring model and solve it through different approximation methods, such as the perturbation method, Newton's harmonic balance method, and the residual harmonic method. We simulate the elastic ring under external hydrostatic pressure, and some loading conditions have been considered. We set contact shape criteria for comparing our proposed methods with the exact solution. We also show some results of self-intersecting shapes.

Why is it important?
In this paper, we show that Newton's harmonic balance formulation of the third order works well enough concerning the exact solutions. It is much simple to implement this model.
