Application of the Stress-Energy Method for Generating Corrugated Board Cushion Curves

Abstract Cushion curves are an important tool used for designing foam cushions, but no commercially available curves exist for corrugated board, despite its growing popularity as a cushioning material. This paper summarizes the theory and recent work applying the stress-energy method and different curve fit models to corrugated board for generating cushion curves. This paper also compares stress-energy predicted deceleration values to actual ASTM D1596 deceleration values as a method of determining whether the stress-energy method is a viable alternative for generating cushion curves for corrugated board. The results of this study suggest that the stress-energy method should not yet be recommended for generating cushion curves for corrugated board.
