Effect of Horizontal Offset on Vertical Compression Strength of Stacked Corrugated Fiberboard Boxes

Effect of Palletized Box Offset on Compression Strength of Unitized and Stacked Empty Corrugated Fiberboard Boxes

The purpose of this study was to evaluate the effect of pallet type, tie-sheet and stack configuration on compression strength of a palletized load of boxes. Four boxes made from similar board grade and different dimensions were selected for this study. The col­ umn stack configuration which represented the control was compared with the 3 stack configurations either on a CHEP® or GMA pallet. Th...

Effect of Relative Humidity on the Optimum Flute Shape for Corrugated Fiberboard

Container stacking strength is an important performance requirement of corrugated fiberboard. The objective of this study is to examine theoretically how fluting geometry affects fiberboard strength and stiffness under standard relative humidity (RH) and high RH conditions. The fluted medium in a corrugated fiberboard is modeled as a connection of curved arc and straight flank segments passing ...

Effect of Through Stationary Edge and Center Cracks on Static Buckling Strength of Thin Plates under Uniform Axial Compression

Thin plate structures are more widely used in many engineering applications as one of the structural members. Generally, buckling strength of thin shell structures is the ultimate load carrying capacity of these structures. The presence of cracks in a thin shell structure can considerably affect its load carrying capacity. Hence, in this work, static buckling strength of a thin square plate wit...

Effect of Loading Rate on the Edgewise Compressive Strength of Corrugated Fiberboard

Comparison of Postbuckling Model and Finite Element Model with Compression Strength of Corrugated Boxes

Conventional 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 employs a finite element model, instead of actual experiments, to generate experimentally d...
