Theoretical Analysis of Equivalent Elastic Modulus of Corrugated Paperboard

Abstract:

A new mathematical method is developed for the calculation of equivalent elastic modulus of UV-type corrugated paperboard. The model is assumed to be composite sandwich structure and to endure the out-of-plane uniform pressure. Force method is used for the derivation of the formula. The influence of the corrugated medium structure on the flat compression strength of corrugated paperboard is investigated as well. The equivalent elastic moduluses of two different sizes of three-layer UV corrugated paperboard are calculated according to the derived formula. The relationship between the thickness and the shape parameters with the flat compressive strength is discussed. The introduction of shape coefficient into this formula can help to optimize the corrugated sandwich structure and its cushioning pads.
