The consideration of the specific local material behavior of short-fiber-reinforced plastics in FEM simulation is comparatively complex. Within the scope of the project, a method will be developed which simplifies this significantly and is numerically efficient.
The consideration of the specific orientation-dependent local material behavior of short-fiber-reinforced plastics in FEM simulation is complex. This is often done by means of multiscale material models which are executed as user routines at runtime of the FEM simulation via suitable interfaces. This is numerically complex, especially in the case of yielding, and sometimes also unstable. Long computing times or a termination of the simulation can result. The calibration of such material models is also complex. Within the framework of the project, a procedure is being developed which represents a significantly simplified and numerically more efficient procedure compared to the state of the art. Standard material models of the respective FEM solver are used as far as possible. For the existing software Converse a module will be developed, which implements the developed procedure in a user-friendly way.
