Crushing analysis of braced metal rings using the equivalent structure technique

This paper presents a development of the equivalent structure technique to account for some of the effects of strain-hardening in structures undergoing plastic bending. The lateral compression of symmetrically deforming braced rings is analysed and the results compared with corresponding experimental data. The effects of strain-hardening on the analytical results both in the small deformation post-collapse régime and at large deformations prior to the onset of unstable deformations are discussed.
