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…
Size-dependent fracture in elastomers: experiments and continuum modeling
Jaehee Lee, Jeongun Lee, Seounghee Yun +4
Elastomeric materials display a complicated set of stretchability and fracture properties that strongly depend on the flaw size, which has long been of interest to engineers and ma…
Large strain micromechanics of thermoplastic elastomers with random microstructures
Hansohl Cho, Jaehee Lee, Jehoon Moon +4
Thermoplastic polyurethanes (TPU) are block copolymeric materials composed of plastomeric "hard" and elastomeric "soft" domains, by which they exhibit highly resilient yet dissipat…
Data-Driven Statistical Reduced-Order Modeling and Quantification of Polycrystal Mechanics Leading to Porosity-Based Ductile Damage
Yinling Zhang, Nan Chen, Curt A. Bronkhorst +2
Predicting the process of porosity-based ductile damage in polycrystalline metallic materials is an essential practical topic. Ductile damage and its precursors are represented by…
Deformation and dislocation evolution in body-centered-cubic single- and polycrystal tantalum
Seunghyeon Lee, Hansohl Cho, Curt A. Bronkhorst +7
A physically-informed continuum crystal plasticity model is presented to elucidate the deformation mechanisms and dislocation evolution in body-centered-cubic (bcc) tantalum widely…
A polyurethane-urea elastomer at low to extreme strain rates
Jaehee Lee, David Veysset, Alex J. Hsieh +2
A finite strain nonlinear constitutive model is presented to study the extreme mechanical behavior of a polyurethane-urea well suited for many engineering applications. The microme…
Anomalous Plasticity of Body-Centered-Cubic Crystals with Non-Schmid Effect
Hansohl Cho, Curt A. Bronkhorst, Hashem M. Mourad +2
Plastic deformations in body-centered-cubic (BCC) crystals have been of critical importance in diverse engineering and manufacturing contexts across length scales. Numerous experim…
