We investigate an approximate approach for compliance‐based topology optimization of short fiber‐reinforced plastic (SFRP) parts. The approximation consists in the replacement of the costly filling and fiber orientation simulation by the solution of an eikonal equation, which determines the principal fiber orientation. The optimization problem is then solved using the classical SIMP method in combination with a transversely isotropic material law and a projected gradient method. (© 2017 Wiley‐VCH Verlag GmbH & Co.
