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.
