Experimental study of crease formation in an axially compressed sheet

Chaieb, S; Melo F.

Abstract

In our study of crease formation in a cylindrical panel subject to axial compression, we found that the maximum vertical deflection ? increases in the orthoradial direction l and saturates when the panel is larger than half a cylinder. The length of the crease X decreases by increasing the panel opening angle, and saturates to a constant value when the opening angle is close to 2 ?. The stress corresponding to initial crease formation goes as 1/R, where R is the radius of curvature of the panel. Profilometric measurements reveal the presence of a region around the singularity where the stress is focused and where the deformation is plastic.
