DETERMINE THE DAMAGE BOUNDARY CURVE FOR THE PACKAGING USING THE FINITE ELEMENT METHOD

Tóm tắt

The damage boundary curve is an important criterion in the packaging design process, especially in assessing the deformation resistance of paper packaging. This study presents a method for quickly determining the damage boundary curve using the finite element method, directly serving the needs of design and optimization of the forming process in the packaging industry. Based on the elastic-plastic homogenization method developed for corrugated core cardboard, an equivalent model for carton boxes subjected to vibration is built. This model significantly reduces the computation time compared to the homogeneous model. Thereby helping to determine the failure limit curve of carton packaging quickly. The method is verified by comparing it with experimental data and shows high accuracy, which is suitable for the strict requirements of high-speed packaging production. The research results open up an effective and time-saving approach in applying the finite element method to the analysis, evaluation, and control of damage in the packaging industry in general.
