Case Study: SABIC achieves highly accurate stiffness and strength prediction with Hexagon Digimat

Accurately estimating ULTEMTM 2300 resin behaviour using the anisotropic modelling approach with Digimat

SABIC, a major global petrochemical manufacturer, needed a more accurate way to predict the material properties of its fiber-filled thermoplastics, like ULTEM™ 2300 resin. The standard isotropic modeling approaches were causing significant overestimations of part stiffness and strength, which hindered optimal product design. To address this challenge, SABIC partnered with vendor Hexagon to utilize their Digimat software for an advanced anisotropic modeling approach.

Hexagon's solution involved using Digimat to create high-fidelity simulations that incorporated flow-induced fiber orientation data from injection molding, providing localized material properties. This anisotropic approach was validated at both the specimen and part level, resulting in a dramatic increase in prediction accuracy. The errors in predicting peak force and displacement were reduced to below 10%, a significant improvement over the 20-40% errors from previous methods. This highly accurate modeling from Hexagon enables SABIC to significantly reduce development costs and improve its product development cycle.
