Abstract

A simplified approach towards a simplified integrative simulation for short
fibre reinforced polymers (SFRP) has been proposed by Gruber and Wartzack.
It uses orientation information from injection moulding simulation directly
inside a structural or crash simulation. For describing the complex material
behavior of SFRP, a layerwise stacking of simple material models is used.
Thus, only standard material models which can be computed efficiently have
to be used. Within the present paper, the simulative approach is to be verified
and validated, i.e. the physical plausibility and the usability for loadcases with
elevated strain rates are examined.
