Abstract

Because of the importance of lightweight constructions, nowadays other materials are more and more substituting components which had previously been made of metals. The usage of short fiber-reinforced plastics instead of metals seems self-evident in many cases because of their high specific strength and the favorable manufacturing processes. For fatigue life prediction a simulation process was established, which takes into account the fiber orientation and distribution as a result of an injection molding simulation. Hypotheses for fatigue life prediction of orthotropic materials have been derived from a lot of tests on specimens, implemented in the standard fatigue software tool FEMFAT and verified so far with component tests.
