The aim of this project is to get deeper insight into the fatigue behaviour of concrete under cyclic compressive loading. It focuses on the evaluation and modelling of the entire damage process during life-cycle by means of various non-destructive measuring techniques. In numerous tests on cylinders h/d = 30/10 cm under different cyclic loading conditions, the crack development and the damage evolution are monitored using acoustic emission analysis and ultrasonic velocity measurement. The final aim will be the definition of a damage descriptor D based on experimental observations, which can be implemented into a numerical model on a meso-mechanical level.
