Residual stresses may be introduced into plastic parts produced by the injection molding process. As a result, the part may warp or experience a reduction in strength. The design of an injection molded product can be improved if the effect of residual stresses on the final shape and performance of the product are predicted accurately. Abaqus and Moldflow can be used for this purpose. The residual stresses generated by the solidifi-cation of the plastic material are computed by Moldflow and transferred to Abaqus using the Abaqus Interface for Moldflow.

A key factor in the design of bottles and packaging con-tainers is performance during conveying. The ability of a bottle to remain standing while traveling through a con-veying plant for production, cleaning, filling, packaging, etc. allows that plant to be automated. If bottles fall or jam during conveying then human intervention is required to correct the situation. Finite element analysis can be used to verify new bottle designs and ensure that changes to current designs will not cause a reduction in conveying performance.

Hot rolling is a basic metal forming technique that is used to transform preformed shapes into final products or forms that are suitable for further processing. The process typically involves passing heated stock pieces through multiple sets of forming rolls until the desired cross-sectional shape is achieved. The important aspects of this manufacturing operation are the elongation and spread of the material during the rolling process.

This study concerns simulation of the forming process of a carton-based package for liquid food (for example, milk or juice), and how the packaging material interacts with the fluid during the forming. The carton-based package is formed inside a filling machine while the fluid is being filled into the package. The carton-based package is thin with low bending stiffness and is thus deformed significantly at small loading. This implies that the forming of the package to a large extent depends on the dynamics of the fluid inside the package.

From a structural point of view, corrugated board would fit on the category of sandwich structures, which in sectors as aeronautics or construction are today commonly analysed using simulation tools that are based on the Finite Element Method.

The Virtual Race Track, VRT, suite of simulations is the most recent addition to the automation tools known as Virtual Package Simulation, VPS, for analyzing the performance of plastic bottles. These new simulations predict the dynamic performance of bottles traveling on conveyors. The objective is to determine if the bottles remain standing after impacting fixed guide rails and gates. The bottles must remain standing to be effectively conveyed. By using ABAQUS to predict this performance, designs can be evaluated much earlier in the product development cycle.

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.
