International conference Multiaxial fatigue and fracture (Proceedings) N2 - The low-cycle fatigue behavior of cc-brass CuZn30 was irtvestigated in uniaxial (tension-compression and torional) and biaxial tests under total strain control at room temperature. Planar-biaxial fatigue tests were carried out on a servohydraulic tension-compression testing machine with and without phase shift using a cruciform specimen geometry with fixed principal stress axes. In phase and out of phase tensiontorsion tests were performed using tube shape specimens on a servohydraulic tensiontorsion testing machine. Microstructural investigations were performed by transmission electron microscopy as well as by scanning electron microscope. For all proportional load cases the equivalent strain amplitude based on a maximum shear strain energy criterion results in a similar hardening behavior and in fatigue life times within a scatter band of three. Out of phase loading results in additional cyclic hardening and reduced life time. Planar glide structures were observed in all tested cases as well as areas of pronounced strain localization in the torsional load cases. No evidence of transition to wavy glide behavior was observed. T2 - ICMFF10 - 10.
