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.

This paper presents several modeling techniques for simulating and optimizing

Automation of analysis routines for designing packages has lead to the development of the

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.

Embossing of polymeric films destined for usage in the personal care marketplace is an industrial process that produces a very fine pattern, barely discernible to the naked eye, yet has a significant influence on some market-driven properties; more bulk, a soft and smooth touch, reduced crinkling noise and lower gloss. However this comes at a cost to the mechanical properties such as stiffness and ultimate strength capability.

ABAQUS is used to simulate interactions of an absorbent personal care product (a diaper), with its user and their environment. This problem, being almost completely driven by complex contact between highly deformable and moving bodies, is a challenging proposition. Advanced contact algorithms, non-linear material models and multi-body dynamic analysis capabilities in ABAQUS are used to successfully study the structural interactions of a diaper, a baby and their environment.

Origami is the art of paper folding. Our entire range of packages is formed from a flat web of packaging material using the origami technique. Virtual and reverse engineering are fundamental for the development of our technology. Complex simulations like extremely nonlinear dynamic events as well as design optimization are part of our daily activity. This paper describes how Simulia’s software with the help of automated tools has been successfully used to simulate the fundamental phases of our forming process driving in some cases its design.

People are less likely to wear hearing protection that is uncomfortable. The overall comfort of the hearing protection is therefore a primary design feature. Methods for evaluating comfort typically include production and use testing of physical prototypes which are expensive and time consuming which reduces the number of design options to test. This work demonstrates the use of computer modeling to predict wearer discomfort by modeling the interaction between ear protection devices and the human ear.
