Latest software from ESI improves composite crash analysis

LinkedIn +

ESI Group has launched a new release of its Virtual Performance Solution (VPS) software. The package now includes new functionality to help OEMs tackle challenges related to the introduction of new materials.

Firstly, thanks to new dynamic re-meshing capabilities, the accuracy of rupture propagation after an impact is now better captured.

Secondly, VPS 2016 includes new advanced composite crash and strength models that enable prediction of the rupture behavior of composite parts and their capability to absorb energy during a crash. The accuracy of composite structural performance prediction is increased by taking into account manufacturing effects, such as fiber orientation, that are inherited from the composite forming process.

ESI has also incorporated extended capabilities for NVH analysis, enabling the prediction of noise radiation, combining the FEM for the structure and the boundary element method for the outside of the car.

The same single-core model is used for the complete vehicle, which enables users to set the correct pre-loading conditions, mandatory for high quality prediction of structural responses. To achieve greater accuracy, the single-core model also integrates frequency dependency and manufacturing history, even for very innovative and advanced materials and production processes. The use of this single-core model for all engineering teams delivers a drastic reduction of development cycles and costs.
