The 4-point bending test is a widely used method to determine material
No commonly accepted evaluation methodology is available for materials showing
non-linear deformation mechanisms.
In the present study micro- and macro-mechanical simulation models of
continuously reinforced metal matrix composites are employed to investigate
thermo-elasto-plasticity and creep in such experiments.
The overall deflection behavior and the underlying mechanisms are identified
revealing the interaction of various micromechanical phenomena.
