Second‐Order Computational Homogenization of Nonlinear Fluid Flow Through Porous Media
ABSTRACT We present a second‐order computational multiscale model for heterogeneous porous media, which allows for the scale bridging of transient fluid‐flow processes through porous materials with non‐separated scales. The formulation connects a homogenized macroscopic scale described by a local theory of grade two with heterogeneous microstructures ...

Microlayer Model: A Nonlinear Finite Strain Viscoelastoplastic Formulation for Asphalt
ABSTRACT The microlayer framework is an innovative and powerful approach for the numerical simulation of heterogeneous materials, such as aggregate‐matrix composites across multiple scales. In this study, the microlayer framework is extended for the first time to account for viscoelastic‐elastoplastic material behavior.

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems
This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the
