Cover Story: This study investigates the mechanical performance and energy absorption capacity of bioinspired hybrid soft–hard structures with gradient lattices. The structures are designed based on the diversity of materials and graded size of the unit cells. Five different graded lattice structures with various relative densities made of soft and hard materials are numerically analysed. The results are validated against experimental data on three-dimensional (3D)-printed lattices and reveal the simulation to be of high accuracy. Dual-soft–hard-material lattice structures are also studied, showing maximum energy absorption and mechanical performance in comparison to single-material lattice structures. View this paper
