“…The results of the fatigue loading show the typical stiffness degradation in the first phase of the fatigue life as well as the crack density increase. The phenomenological based stiffness degradation model of Adden [2] is applied to the recorded crack density data to model stiffness degradation. After crack onset can be detected the theory shows good agreement with the experimental ones.…”

“…The recorded crack density data is used with an in-house calculation tool to predict stiffness degradation. The tool is based on the phenomenological stiffness degradation model of Adden [2]. This model was implemented by Adam in [7] into a calculation tool (ELDA) which is used to calculate the stiffness degradation by given crack density data for the described fatigue tests.…”

In this paper experiments on the fatigue behavior of flat and tubular Glass Fiber Reinforced Plastics (GFRP) specimens with three different layups ([0/905/0], [0/902/01/2]s and [0/±45/01/2]s) are presented. The experiments are conducted to study the mechanics under cyclic tension-tension loading (R=0.1) until crack saturation (CDS). Fatigue testing is performed below the critical static load level where first matrix cracks can be observed. Therefore Load Levels (LLs) are derived from crack evolution curves obtained by static tests under usage of transmitted light photography. The shear lag model of Berthelot [1] is applied to the two cross-ply specimens to predict crack evolution. The results show good agreement between the prediction and the experimental data. Deviations can be found in prediction of crack evolution in [0/902/01/2]s-specimens. For predicting fatigue stiffness degradation the phenomenological model of Adden [2] is used. The results show good capabilities for predicting stiffness degradation after crack onset.
