Pharmaceutical high barrier blister packages are manufactured from aluminium-polymer laminate foils (e.g. consisting of PA-Al-PVC layers). By a cold stretch forming process cavities are formed. The aim of this work is to determine a homogenized elastic-plastic description of the laminate by micromechanics. Therefore, a microstructural model is developed where the layers are mapped in a representative volume element. The obtained homogenized material model is applied to simulate the stretch forming to gain more insight into the forming process.
