Multiaxial fatigue analysis of orthotropic materials*

  • C. Gaier, B. Unger and H. Dannbauer

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.
