Finite element analysis of anisogrid lattice structures

Anisogrid lattice structures are gaining increasing interest due to their exceptional physical and mechanical properties. Enabled by additive manufacturing techniques, these structures offer high strength-to-weight ratios, making them ideal for lightweight mechanical components. This study aims to develop a finite element model to evaluate the stress distribution in anisogrid lattice structures. A sensitivity analysis was conducted on geometric parameters to identify their influence on the stress state. The results provide valuable preliminary insights into how the geometry of anisogrid lattices can be optimized to enhance their performance and contribute to the design of high-performance, lightweight metamaterials suitable for various engineering applications, including aerospace, automotive and structural fields.
