Advanced Simulation of 3D Glass Bottle Forming with Abaqus

Production of glass bottles requires blowing of the glass after entrance of a gob of molten glass in the blank mould. The final shape of the bottle is highly dependent on the viscosity of the glass, the blow-pressure and the temperature distribution in the glass and the mould and simulation of this complicated process enables optimization of the process conditions. During simulation of blowing of the glass, the mesh has to be adapted due to the extreme deformations of the mesh. To reduce the user-time and to be able to run this kind of analyses automatically based on an arbitrary base-geometry, a completely automated remeshing/rezoning procedure is set-up. Using the automated remeshing capability, simulations of the glass bottle forming process have successfully been performed, enabling for example optimization of process settings.
