High Pressure Suppression of Plasticity due to Over-Nucleation of Shear Strain
Brenden W. Hamilton, Timothy C. Germann
High pressure shear band formation is a critical phenomenon in energetic materials due to its influence on both mechanical strength and mechanochemical activation. While shear band…
Using Limited Neural Networks to Assess Relative Mechanistic Influence on Shock Heating in Granular Solids
Brenden W Hamilton, Timothy C. Germann
The rapid compaction of granular media results in localized heating that can induce chemical reactions, phase transformations, and melting. However, there are numerous mechanisms i…
Interplay of Mechanochemistry and Material Processes in the Graphite to Diamond Phase Transformation
Brenden W. Hamilton, Timothy C. Germann
he manifestation of intra-molecular strains in covalent systems is widely known to accelerate chemical reactions and open alternative reaction paths. This process is moderately und…
Energy Localization Efficiency in TATB Pore Collapse Mechanisms
Brenden W. Hamilton, Timothy C. Germann
Atomistic and continuum scale modeling efforts have shown that shock induced collapse of porosity can occur via a wide range of mechanisms dependent on pore morphology, shockwave p…
Predictive Scale-Bridging Simulations through Active Learning
Satish Karra, Mohamed Mehana, Nicholas Lubbers +12
Throughout computational science, there is a growing need to utilize the continual improvements in raw computational horsepower to achieve greater physical fidelity through scale-b…
Machine Learning of consistent thermodynamic models using automatic differentiation
David Rosenberger, Kipton Barros, Timothy C. Germann +1
We propose a data-driven method to describe consistent equations of state (EOS) for arbitrary systems. Complex EOS are traditionally obtained by fitting suitable analytical express…
