Abstract

This article discusses the nonlinear behavior of the corrugated packaging during compression. The model of this behavior is a load-displacement curve with an ascending branch, a peak point and a descending branch. In some cases, the descending branch shows signs of plastic transition and/or loss of stability of the container walls. The purpose of this work is to predict the transition point of a corrugated container into a plastic (or pseudo-plastic) state. This condition is unacceptable because there are residual deformations that reduce the quality of the container. The article proposes and implements an approach based on the joint application of the well-known equation of the dependence of the load on displacement and the differential fracture criterion. The simulation results are consistent with experiments known from the literature. The conducted research makes a certain contribution to the creation of new tools, the use of which expands the possibilities of analyzing the mechanical behavior of corrugated cardboard containers for the purpose of rational use of resources in accordance with the concept of sustainable development.
