Glass Container software – ELFEN GD

ELFEN GD is a self contained suite of numerical modelling programs which are designed to provide glassmakers with decision support system tools to aid in the design, production and quality control of glass containers. The product has a customised user interface which employs glass industry terms for ease of use, enabling proficiency to be quickly developed by a range of users. Users can simulate the forming of containers and assess their integrity under a variety of loading conditions.

The two main modules, Forming and Design (stress analysis) can be linked to facilitate the development of new container designs.

ELFEN GD forming

The forming module has been designed to simulate the forming process of round glass containers, from gob delivery through parison formation, invert and final blow to mould open. The types of forming processes modelled include BB, PB and NNPB.

ELFEN GD design

The Design module allows stress analysis of a finished container under a variety of conditions, including:

Head loads and/or internal pressure loading
Impact (pendulum tests, filling line collisions, drop loads)

Assessment of a container’s integrity can be made by comparing the predicted results against experimentally determined failure stress curves. Both round and non-round containers may be analysed.

Platforms

The ELFEN GD suite runs on a PC under most versions of Microsoft Windows.
