Original Abstract

An original and efficient testing setup has been designed in collaboration of the Institut of Physical Engineering and the Erich-Schmid Institute of Materials Science in Leoben. This device allows simultaneous fatigue crack propagation in pure shear modes II and III in a single specimen. The specimens were made of austenitic (x5NiCrTi26-15) steel and loaded under shear stress range from 80 MPa to 220 MPa with loading ratio R = 0.1. The stereophotogrammetrical reconstruction of the fracture surface morphology in the scanning electron microscope was performed. The analysis showed that the 3D topology of factory-roof patterns in torsion loading is very similar to that identified in the case of cyclic shear loading.
