Beschreibung
Experiments on hydraulic components indicated that hydraulic pressure causes an additional load on the crack faces and that a viscous fluids do not flow out during rapid load changes, which reduces the effective damage amplitude. In this work, a simulation of the fluid-structure interaction is modeled with an averaged thin-film flow and coupled with a mechanical model. The simulation of the oil flow in the crack and the crack provides a better understanding of the FSI and its impact on fatigue.
