摘要
We introduce a surrogate modeling approach to approximate the mechanical responses of objects manufactured by 3D printers. In particular, we propose a systematic procedure where material parameters of the low-fidelity orthotropic Gurson-Tvergaard-Needleman (GTN) model are inferred from microstructures generated from the high-fidelity discrete element simulations that replicate the additive-manufactured procedure. The calibrated low-fidelity model is validated against experimental data.
