Lightweight design of polymeric thin-walled components: Latticization and elastic–plastic homogenization
In this published work the mechanical behavior of Polyamide 12 (PA12) lattice structures, produced with Multi Jet Fusion (MJF) is investigated, aiming to meet the demand for lightweight and structural strength. Combining experimental tests, simulations, and theoretical modelling, a homogenized material was proposed to predict the elastic–plastic response of these lattice structures. The model incorporates periodic boundary conditions, Hill’s yield criterion, and the Levy-Mises flow rule to account for anisotropic plasticity and directional hardening. Numerical results closely matched experimental data, demonstrating the model’s accuracy.
