Fracture Toughness Analysis of Aluminium Foil and its Adhesion with LDPE for Packaging Industry

Abstract: The purpose for this thesis is to investigate the mechanical properties of the aluminum foil used for packaging industry, the reaction of the material exposed to loading and the crack sensitivity coupled to the maximum strain in the material after loading. This investigation will be based on both physical experiments and numerical simulations in the Finite Element Method program ABAQUS for with and without initial crack of different length. The simulations purpose is to get a better understanding of the different material parameters and the physical tests serves to verify the numerical model and to prove its credibility. The final model in ABAQUS will be used to test the parameters in an extensive parameter study with the ambition to find an ultimate combination of the parameters both for the material and its adhesion with LDPE.
