Research: Advancements in package opening simulations for beverage packaging

The fracture mechanical phenomenon occurring during the opening of a beverage package is rather complex to simulate. Reliable and calibrated numerical material models describing thin layers of packaging materials are needed. Researchers at Tetra Pak® Packaging Solutions in Sweden show that it is possible to select material models in conjunction with continuum material damage models, adequately predicting the mechanical behavior of failure in thin laminated packaging materials. Comparison of the experimental opening and the virtual opening, showed a good correlation with the developed finite element modeling technique. An article about the research is published in Procedia Materials Science 3.
