Modified Compression Test of Corrugated Board Fruit Tray: Numerical Modeling and Global Sensitivity Analysis

Abstract

This article presents a modified configuration of the box compression test (BCT), which reflects the actual behavior of the vegetable or fruit trays during transport and storage. In traditional load capacity tests, trays are treated as classic transport boxes, i.e., they are compressed between two rigid plates, which does not take into account the specific geometry of this type of packaging. Both the boundary conditions and the loads acting on the tray were modified. The paper presents the concept of a new test, as well as numerical models and a sensitivity analysis of the modified BCT to the basic geometrical dimensions of the tray. The conducted research clearly shows that the proposed configuration of the load-bearing capacity test of a tray is closer to the actual operation of the packaging. As a result, most of the parameters that are not active under the conditions of the classical BCT become more important in the new configuration, which corresponds to the observations on the real performance of the packaging.

A Simplified Dynamic Strength Analysis of Cardboard Packaging Subjected to Transport Loads

“…The overall aim of the paper is to derive a numerical tool for computing the changes in the compression strength of a particular box after representative environmental vibration during transportation. Therefore, as presented in Figure 3 , the static finite element analysis of the stress-free state box was first performed and was preceded by a buckling analysis to determine the numerical imperfection field, in which was similar to [ 3 , 4 ]. From this step was determined, i.e., the compression strength of the box before the VRV test.…”

“…Therefore, it is essential to optimize the weight of the packaging, especially now that the shipping industry is striving for sustainable development—zero waste, zero energy balance, etc. The first step for optimizing packaging should be understanding which factors play a crucial role in determining the strength of the packaging due to a particular load mode [ 2 , 3 , 4 ].…”

Mechanical Characterization of Corrugated Board: Sensitivity Analysis in Design of Experiments

“…Therefore, in computational models, simulations of laboratory tests were always carried out using the displacement (or rotation) control. All material parameters used in these study were taken from our previous research for representative thin, medium and thick boards [52,53].…”
