Abstract Scope |
Multi-lattice structures, made possible by additive manufacturing and characterized by diverse lattice configurations, provide substantial flexibility in meeting complex engineering requirements. This flexibility arises from the tunable physical properties of lattices achieved through a variety of geometries, topologies, and densities. However, despite these advantages, the fatigue behavior of such structures remains hard to predict and largely unexplored, impeding the widespread application of these advanced design and manufacturing methods due to reliability uncertainties. This paper aims to review current methods of fatigue life prediction, primarily tailored for smooth or uniform lattice structures. It also identifies the existing knowledge gaps and practical challenges inherent in predicting the fatigue life of multi-lattice structures, which exhibit variations in both micro- and meso-structural patterns. Moreover, we explore the opportunities present at the interaction of numerical simulation and machine learning for enabling high-fidelity and efficient simulations. |
