Material and structural failure criterion of corrugated board facings

A failure stress criterion for corrugated board facings is presented. The f ailure criterion is based on material failure and structural local buckling failure, which are evaluated in a combined analysis procedure. The failure stress is compared with collapse experiments on corrugated board cylinders and the failure stress presented herein is seen to be in much better agree ment with the measured stresses than the Tsai-Wu failure criterion alone. T he fluting wavelength of the corrugated board is also varied for the purpos e of strength sensitivity analysis of corrugated board. (C) 2000 Elsevier S cience Ltd. All rights reserved.
