The makers of ADINA software have just announced that “in response to customers’ requirements,” ADINA supports the Bergstrom-Boyce and Three-Network viscoelastic material models. According to ADINA, “These sophisticated material models allow users to capture complex viscoelastic behaviors of polymeric components.” Both of these models are part of the PolyUMod Library of user-material models developed by Veryst to help solve difficult polymer design problems.
The PolyUMod library provides advanced material models for finite element modeling of engineering polymers and biomaterials, and plugs into an FE solver to enable more accurate predictions than what is possible with typically available material models. PolyUMod covers virtually all polymer systems, including thermoplastics, thermosets, elastomers, foams, filled plastics, and biomaterials. Specific models also have been developed for particular formulations such as fluoropolymers, PLA (polylactic acid), and UHMWPE (ultra-high molecular weight polyethylene).
