RISAtomic-to-Continuum Multiscale Modeling of Defects in Crystals With Nonlocal Electrostatic Interactions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work develops a multiscale modeling framework for defects in crystals with general geometries and boundary conditions in which ionic interactions are important, with potential application to ionic solids and electric ...

Hierarchical MPM-ANN Multiscale Terrain Model for High-Fidelity Off-Road Mobility Simulations: A Coupled MBD-FE-MPM-ANN Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new hierarchical multiscale terrain model is developed using the material point method (MPM) to enable effective modeling of large terrain deformation for high-fidelity off-road mobility simulations. Unlike the Lagrangian ...
Enhancing Hierarchical Multiscale Off-Road Mobility Model by Neural Network Surrogate Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hierarchical multiscale off-road mobility model is enhanced through the development of an artificial neural network (ANN) surrogate model that captures the complex material behavior of deformable terrain. By exploiting ...
