摘要

A method for the experimental determination of bifurcation in stability and supercritical forms of rotation of elastic ring with respect to its diameter includes determination of the value of angular velocity of rotation at coming to which the ring goes out of the initially flat form of spatial rotation (sphere of revolution) and goes to supercritical spatial forms of rotation (paraboloids of revolution). Deformed state of the flexible elastic ring before bifurcation instability and after bifurcation in stability at quasi-static load (rotation) is determined.
