E-Xstream Launch New Digimat Release

e-Xstream engineering has announced the new release of Digimat version 5.0.1.

The new capabilities in this release significantly improve the user friendliness of analysing fibre reinforced plastics and the accuracy of analysing unidirectional (UD) and woven composites.

The new release supports the setup of 3D analyses with Marc, MSC Nastran, Abaqus, Ansys, and LS-Dyna based on Moldflow, Moldex3D, Sigmasoft or Timon 3D processing results. Jobs can either be run and monitored on a local computer or packaged for the remote solution on a cluster. Digimat-RP is an intuitive 3-step process that enables a part engineer (not necessarily a material expert) to do predictive analysis of plastic parts using one single process oriented product (RP) instead of the original four. RP is easy to learn and to use by “non-experts”. The experts can continue to use the general-purpose building blocks and prepare the models for easy use in RP.

Digimat now offers a Matzenmiller-Lubliner-Taylor (MLT) based model for the progressive failure of UD composite materials. Failure progression includes individual damage control functions as well as stabilisation of failure progression for coupled analyses. In initial studies, 97% accuracy on open hole tension test could be reached.

The Hybrid solution method has been enhanced to support elastic, elastoplastic and elasto-viscoplastic material models for woven composites including per-phase failure. Anisotropic thermal conductivity can also be used in coupled analyses with Digimat-CAE/Abaqus. Thermo-mechanical analyses are available via Digimat-CAE/Marc. Robustness has been improved by offering RE of TEP material models in MX and the support of TE and TEP within the Hybrid solution method.
