Abstract: Collapse behavior of aluminum tubes of square and rectangular crosssections,when compressed between two identical narrow width indenters placed symmetrically in parallel alignment, is examined. Experiments were performed wherein the angle between the axes of tube and indenters was varied from 0 to 90Z Load compression curves and deJormation histories of typical specimens are presented. The collapse of the tubes was seen to be generally symmetrical, though asymmetries were observed in some tubes.Considering only the symmetrical mode of dejormation, an analysis is presentedJor constructing the load-compression curves as well as the shape of the deforming tube. The analysis considers the energy absorbed in stationary and rolling plastic hinges which are Jormed in the collapsing tube. Computed results thus obtained compare well with the experiments.
