Mechanical isotropy of heterogeneous octahedral materials
Jehoon Moon, Seunghwan Lee, Gisoo Lee +2
An octahedral network has been widely used as a fundamental building block for diverse architected materials. Here, we demonstrate that heterogeneous octahedral materials can achie…
Bayesian inference and uncertainty quantification for modeling of body-centered-cubic single crystals
Seunghyeon Lee, Thao Nguyen, Darby J. Luscher +3
Uncertainties in the high-dimensional space of material parameters pose challenges for the predictive modeling of bcc single crystals, especially under extreme loading conditions.…
Stiffness, strength, energy dissipation and reusability in heterogeneous architected polycrystals
Seunghwan Lee, Hansohl Cho
We design, fabricate and test heterogeneous architected polycrystals, composed of hard plastomers and soft elastomers, which thus show outstanding mechanical resilience and energy…
Extreme resilience and dissipation in heterogeneous disordered materials
Jehoon Moon, Gisoo Lee, Jaehee Lee +1
Long range order and symmetry in heterogeneous materials architected on crystal lattices lead to elastic and inelastic anisotropies and thus limit mechanical functionalities in par…
