Shear-wave-induced softening and simultaneous compaction in dense granular media through acoustic lubrication at flow heterogeneities
Charles K. C. Lieou, Jerome Laurent, Paul A. Johnson +1
We report the simultaneous softening and compaction of a confined dense granular pack in acoustic resonance experiments. Elastic softening is manifested by a reduction of the shear…
Dynamical heterogeneities in liquid and glass originate from medium-range order
Charles K. C. Lieou, Takeshi Egami
Slow relaxation and plastic deformation in disordered materials such as metallic glasses and supercooled liquids occur at dynamical heterogeneities, or neighboring particles that r…
Mean-field model for the Curie-Weiss temperature dependence of coherence length in metallic liquids
Charles K. C. Lieou, Takeshi Egami
The coherence length of the medium-range order (MRO) in metallic liquids is known to display a Curie-Weiss temperature dependence; its inverse is linearly related to temperature, a…
Thermomechanical conversion in metals: dislocation plasticity model evaluation of the Taylor-Quinney coefficient
Charles K. C. Lieou, Curt A. Bronkhorst
Using a partitioned-energy thermodynamic framework which assigns energy to that of atomic configurational stored energy of cold work and kinetic-vibrational, we derive an important…
Thermodynamic theory of crystal plasticity: formulation and application to polycrystal fcc copper
Charles K. C. Lieou, Curt A. Bronkhorst
We present a thermodynamic description of crystal plasticity. Our formulation is based on the Langer-Bouchbinder-Lookman thermodynamic dislocation theory (TDT), which asserts the f…
Strain localization and dynamic recrystallization in polycrystalline metals: thermodynamic theory and simulation framework
Charles K. C. Lieou, Hashem M. Mourad, Curt A. Bronkhorst
We describe a theoretical and computational framework for adiabatic shear banding (ASB) and dynamic recrystallization (DRX) in polycrystalline materials. The Langer-Bouchbinder-Loo…
