The load carrying capacities of circular rings with arc-shaped supports

Abstract This paper describes the quasi-static compression of metallic thin-walled circular rings with arc-shaped supports. An approximate analysis based on the ‘Equivalent Structure Technique’ is presented to estimate the load carrying capacity of circular rings with arc-shaped supports and the positions where plastic hinges form. Good agreement is found, between the experimental values and those predicted by this approximate theory. The effect of the support arc angle is also considered.
