Seed fund project C05

Simulation of the fatigue behaviour of carbon reinforced concrete components under changing cyclic loads

Carbon reinforced concrete components have a high stiffness and a comparatively low mass. This significantly increases the eigenfrequencies and leads to significantly higher load cycle numbers in the same periods of time compared to classically reinforced concrete components. Since a longer service life is also sought, fatigue plays an even more important role than for conventional concrete components.

In this seed fund project, the newly developed eXtended Phase-Field Method is extended by a fatigue model and tested for various changing, cyclic loads typical of carbon concrete structures. The fatigue crack model takes into account not only the decrease in stiffness, but also the strain history dependent decrease in strength of the material.
