Barreling of a short cylinder in compression

Abstract

Large deformation behaviour of aluminium and low carbon steel short cylinders of various diameters and height to diameter ratios, loaded axially in a simple compression test without using any lubricant, is examined. Typical histories of deformation of the cylindrical surface and the end face are presented with a view to studying the nature and the extent of free surface barreling, its folding into the end face and effects of specimen size thereon. The results reveal that the profile of a deforming specimen can sensibly be approximated by an arc of a circle only after the onset of folding.
