Buckle Contours in an Axially Compressed Circular Cylindrical Shell

摘要

Experimentally determined buckle contours at initial instability for an axially compressed aluminum right circular cylinder of 3.35 inches in diameter and 0.0025 inch of wall thickness are presented and analyzed. The results show that for buckle amplitudes of as low as 2.8 times the wall thickness there is strong evidence of plastic deformation. (Author)
