DescriptionConventional compression strength formulas for corrugated fiberboard boxes are limited to geometry and material that produce an elastic postbuckling failure. Inelastic postbuckling can occur in squatty boxes and trays, but a mechanistic rationale for unifying observed strength data is lacking. This study combines a finite element model with a parametric design of the geometry and material characteristics affecting the critical buckling stress of box panels to examine their postbuckling response. The finite element model enables a broad scope of simulated panels to be examined economically. Results lead to a postbuckling model fit to the predictions and a better understanding of how to unify elastic and inelastic failure data from actual experiments and form a more general box strength formula.
