The manufacturing processes of fiber-reinforced composites have a distinct impact on the final fiber structure. Thus, effective local material properties are determined by the manufacturing process. Process simulation is capable to predict the fiber structure after manufacturing. Therefore, it is of utmost interest to consider this information along a Virtual Process Chain in downstream simulation approaches.

Our ABAQUS/CAE add-on SimuChain enables to consider manufacturing effects downstream FEA. This includes the export of the fiber structure obtained with our process simulation approaches SimuDrape and SimuFill, as well as Moldflow simulations. Moreover, the mapping of related state variables from a source mesh onto a target is enabled and required material cards are created through homogenization and clustering.

The result of SimuChain is an ABAQUS/CAE material card ready to be submitted for analysis.

How does it work?

SimuChain covers in combination with the MpCCI Mapper developed by Fraunhofer SCAI and supplied by the scapos AG all steps to consider manufacturing effects predicted by process simulation in an ABAQUS FEA. As an official reseller of the MpCCI Mapper, we deliver both components as a single solution. The only thing you need additionally is a license and working knowledge for ABAQUS/CAE.

The starting situation for SimuChain is the fiber structure on the source mesh predicted by process simulation. This information is exported in a neutral exchange format (vtk: visualization toolkit). Currently, our process simulation approaches SimuDrape and SimuFill, as well as Moldflow, are supported. Upon request, we are happy to implement an interface to any other software package.

Next, the target mesh is exported also in a vtk file and the information from the source mesh is mapped onto the target mesh by MapLib. All these steps are conducted using our ABAQUS/CAE (GUI) plugin.

Finally, mapped data is imported into ABAQUS/CAE and material cards are generated. This includes a homogenization and clustering of the effective and local material properties. Based on this, material cards considering the manufacturing effects from process simulation ready to be submitted for FEA are obtained.
