Advancing Material Modeling in Hydrocodes Beyond Equations of State
Tim A. Linke, Dane M. Sterbentz, Jean-Pierre R. Delplanque +5
We present a multiscale simulation framework that couples the Finite Element Method with molecular dynamics. Bypassing traditional equations of state (EOS) by using in-line atomist…
A Concurrent Multiscale Framework Coupling Direct Simulation Monte Carlo and Molecular Dynamics
Tim Linke, Dane Sterbentz, Niels Grønbech-Jensen +2
We present a new method to couple the Direct Simulation Monte Carlo (DSMC) algorithm with molecular dynamics (MD). The coupling approach generalizes prior coupling methods using a…
Explosively driven Richtmyer--Meshkov instability jet suppression and enhancement via coupling machine learning and additive manufacturing
Dane M. Sterbentz, Dylan J. Kline, Daniel A. White +10
The ability to control the behavior of fluid instabilities at material interfaces, such as the shock-driven Richtmyer--Meshkov instability, is a grand technological challenge with…
Modification of Jet Velocities in an Explosively Loaded Copper Target with a Conical Defect
Michael P. Hennessey, Finnegan Wilson, Grace I. Rabinowitz +8
In this work, the design and execution of an experiment with the goal of demonstrating control over the evolution of a copper jet is described. Simulations show that when using sim…
Data-Driven Autoencoder Numerical Solver with Uncertainty Quantification for Fast Physical Simulations
Christophe Bonneville, Youngsoo Choi, Debojyoti Ghosh +1
Traditional partial differential equation (PDE) solvers can be computationally expensive, which motivates the development of faster methods, such as reduced-order-models (ROMs). We…
Reducing Richtmyer Meshkov Instability Jet Velocity via Inverse Design
Dylan J. Kline, Michael P. Hennessey, David K. Amondson +8
In this work, we detail a novel application of inverse design and advanced manufacturing to rapidly develop and experimentally validate modifications to a shaped charge jet analogu…
