Due to the visco-elasto-plastic material behavior, the added energy to concrete specimens during fatigue tests is transformed into another form of energy. Besides the description of the energetic material behavior of concrete, the elastic and the plastic part of the energy as well as the dissipation energy are analyzed for different specimens. Especially the dissipation energy shows a correlation with the damage process as a result of the cyclic loading. Regarding this correlation, a new energetic damage model is introduced. With this model, a degree of damage during the tests and the development of the damage parameter over the load cycles can be determined. First tests with the developed model show good and plausible results.
