Why Do Two-Piece Cans Collapse or Buckle? The Physics of DWI Structural Failure Reference Standard: ISO 9001:2015 Quality Management Systems & ASTM D7030 (Standard Test Method for Short Term Creep Performance of Corrugated Fiberboard Containers under Constant Load) Short Answer Structural failures in two-piece cans, such as axial crushing and dome reversal, are primarily governed by crystallographic slip in the ultra-thin 0.09mm DWI sidewalls and geometric bifurcation under hydrostatic pressure. These catastrophic deformations occur when internal gas expansion or external vertical loads exceed the Taylor Factor limits of the 3104-H19 aluminum alloy grain structure. The Crystallographic Slip Vector: Dislocation Density in DWI Sidewall Ironing The manufacturing of a two-piece aluminum … 続きを読む
