Investigating the mechanical behavior is an important point for evaluating the mechanical reliability of additively manufactured (AM) lattice structures. First, the lattice structures were experimentally tested under compression loading. In order to identify the local damage behavior and visualize local strains, digital image correlation (DIC) was used in situ. Additionally, compression tests were numerically simulated with Abaqus, applying the Johnson‐Cook failure model. The numerical results were compared and validated with the experimental data. Moreover, manufacturing‐related imperfections and their influence on the structural behavior were analyzed and taken into account in the numerical simulations.
