Mixed Mode Fracture Behavior of 3D Printed Nanocomposites

The fracture behavior of 3D printed nanocomposites in mixed mode loading conditions is investigated in this study. Nanocomposites, owing to their tailored microstructures and enhanced mechanical properties, are increasingly employed in various engineering applications. However, their fracture mechanics, particularly under mixed mode loading, remains relatively unexplored. This research employs experimental and computational methods to analyze the crack growth and fracture toughness of 3D printed nanocomposites under different modes of loading, focusing on the interaction between various reinforcing nanoparticles and the polymer matrix. The findings reveal significant insights into the fracture mechanisms, critical energy release rates, and crack path deviations observed in mixed mode conditions. Such understanding is crucial for optimizing the design and performance of nanocomposite materials in structural applications where complex loading conditions are prevalent.
