The stability of a ring confined by a rigid boundary, subjected to circumferential end loads is investigated by an experimental approach. Dimensional analysis was used to establish the basic relationship of the critical buckling stress with material properties, geometric dimensions and initial geometric imperfections. The coefficients in the relationship were obtained experimentally. Compared to other theoretical methods, this approach is very simple, straightforward and accurately fits the experimental data. Therefore, it is suitable for practical applications.
