#15710, Plate Stiffness Identification of Corrugated Fiberboard with VFM
Corrugated fiberboard is the most prevalent packaging material used for shipping containers. Nearly 90% of manufactured goods in the world are packaged and/or shipped in these containers. Container failure damages the product that is supposed to be protected. Damage to liquid containers may eventually lead to losses in nearby containers. The dominant failure mechanism of these containers is plate buckling. The objective of this work is to identify the plate stiffnesses of corrugated fiberboard for use in container modeling. Plates were 38 cm square and held to a rigid frame. Out-of-plane loading was applied, and out-of-plane deformation was measured with digital image correlation. Various load levels, load locations, and support conditions were utilized to produce a large, robust data set. Resulting plate curvatures were used in a virtual fields method procedure to identify the components of the plate stiffness tensor. These stiffnesses were compared to those measured by traditional methods.
