PhD Student (f/m/d) for numerical and experimental investigations of crack propagation behaviour in hydraulic components

The work is to be performed a part of a DFG project carried out in cooperation with the Fraunhofer-Institute for Mechanics of Materials IWM (Freiburg) and two further scientific groups. The candidate for the actual position should develop an analytical fatigue crack growth model taking account of time-dependent stress fields resulting from the fluid-structure interaction, environmental effects promoting accelerated crack propagation, and crack closure effects due to plastic deformations at the crack tip. For validating the crack growth model, a series of fatigue crack growth tests are to be conducted both in air and in hydraulic oil, using specimens with different crack geometries.
