摘要: Abstract An inextensional collapse mechanism is considered for the crumpling of thin-walled, grooved tubes and without any discontinuities (non-grooved), when subject to axial load. Shortening tube (or shell) height achieved by folding in a non-aximmetric diamond mode about stationary circumferential inclined plastic hinges; initiated at thinnest section (groove) spreads along various rings grooves which consists, passage as travelling hinge. Expressions mean load shell material rigid-perfectly are developed. Predicted loads based on modes encountered, compared with those obtained experimentally, using rigid PVC constant length groove dimensions (depth length), found be good agreement.
