Abstract

Experiments in which metal rings are compressed to large deflections by a pair of opposed concentrated loads reveal a load-deflection characteristic which is at variance with the simple theory based upon rigid-perfectly plastic behaviour. This problem is analysed using a model which incorporates strain hardening in an approximate fashion and it is shown how the discrepancies between the experiments and the simple theory arise. The results of the theory are presented in non-dimensional form and it is shown that the varieties of response depend upon the value of the parameter mR = (6σ0R/Eph) 1 2. The results relate to early work concerned with the effects of strain hardening on the post-collapse behaviour of frame structures and they are compared with similar analyses of rings crushed between flat plates.
