McKee’s formula is widely used to predict the compression strength (CS) of corrugated boxes and panels. It can accurately estimate the compression strength of boxes that are within a practical size range, but recently, larger and smaller corrugated boxes than before have been extensively developed. Therefore, there is a need for a CS prediction formula that works beyond the application range of McKee’s formula. Recent researches consider the failure mode as a combination of collapsing and buckling failure and remove the constraints and the assumptions associated with McKee’s formula. This makes it possible to more accurately estimate the CS of boxes that are not covered by McKee’s formula. Many CS formulae are derived logically from material mechanics, but doing so can make it difficult to account for various actual behaviors in detail up to when the box fails. Instead, by analyzing the behavior up to failure in detail, we explored relationships that could account for the CS consistently based on its behavior.
