Interacting Damage Mechanisms in Laminated Composites Subjected to High Amplitude Fatigue
This manuscript provides a combined computational-experimental investigation of the interaction of damage mechanisms in carbon fiber–reinforced polymer (CFRP) laminated composites subjected to fatigue loading. The investigations particularly focus on laminates, whose behavior demonstrates strong interactions between the relevant damage modes. Numerical investigations are performed using a spatiotemporal computational homogenization-based multiscale life prediction model. The computational approach relies on a model order reduction methodology to develop a meso model that can capture the relevant failure mechanisms in a computationally efficient manner. The model was calibrated using a suite of experimental data from the static and fatigue response of simple laminates made of the same constituents. The calibrated model along with experimental observations from acoustic emission and X-ray computed tomography were employed to understand the relative roles of delamination and splitting and their interactions in controlling fatigue failure processes in CFRPs.
