Center for micromorphic multiphysics porous and particulate materials simulations within exascale computing workflows

Subtopic: Thermomechanics of plastic-bonded granular materials

Sponsor: Predictive Science Academic Alliance Program (PSAAP), ASC-NNSA-DOE

Duration: 7/1/2020 - 6/30/2025

Role: Senior Personnel


The overall objective of the Center is to simulate with quantified uncertainty, from pore-particle-to-continuum-scales, a class of problems involving granular flows, large deformations, and fracture/fragmentation of unbonded and bonded particulate materials, as well as porous cellular materials. The Center research will usher in a new era of higher fidelity multiscale multiphysics computation through large deformation micromorphic continuum field theories informed by DNS through the latest ML techniques calibrated and validated against a rich experimental data set. Our group's role in this project is to perform experimental (at macroscale) and theoretical mechanics (at continuum level) research on the thermomechanical behavior of bonded granular materials with the scope of energy and defense applications.

Length and time scales involved in this collaborative experimental and modeling effort for plastic bonded granular materials.
