Material and structural failure criterion of corrugated board facings

A failure stress criterion for corrugated board facings is presented. The failure 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 agreement with the measured stresses than the Tsai¯Wu failure criterion alone. The fluting wavelength of the corrugated board is also varied for the purpose of strength sensitivity analysis of corrugated board
