      abstract     = {To overcome the intrinsic brittleness of tungsten (W), a
                      tungsten fiber-reinforced tungsten-composite material (Wf/W)
                      is a possible solution. The introduction of energy
                      dissipation mechanisms like fiber bridging or fiber pull-out
                      by means of an engineered interface between fiber and matrix
                      mitigate the brittleness of tungsten and lead to a
                      pseudo-ductile material behaviour. The push-out test of
                      single-fiber samples is an experimental method to
                      investigate the properties of the interface between fiber
                      and matrix of composite materials. It is widely used for the
                      investigation of ceramic composites. This method was also
                      used to investigate the debonding and frictional properties
                      of the Er2O3 interface region between fiber and matrix of
                      Wf/W single-fiber samples made by CVDand HIP-processes. In
                      this article finite element calculations are used to get a
                      better understanding of the processes acting in the
                      interface during a push-out test of Wf/W. A detailed
                      overview of the debonding progress and of the corresponding
                      stress states of the interface during the different stages
                      of the test is presented. In addition the sensitivity of the
                      push-out behaviour regarding the different interface
                      properties and the plastic flow curve of the tungsten fiber
                      are investigated.},
