Mathematics for energy systems: Methods, modeling strategies, and simulation
Nicklas Jävergård, Grigor Nika, Adrian Muntean
We offer an insight into our mathematical endeavors, which aim to advance the foundational understanding of energy systems in a broad context, encompassing facets such as charge tr…
A Bound Preserving Energy Stable Scheme for a Nonlocal Cahn-Hilliard Equation
Rainey Lyons, Grigor Nika, Adrian Muntean
We present a finite-volume based numerical scheme for a nonlocal Cahn-Hilliard equation which combines ideas from recent numerical schemes for gradient flow equations and nonlocal…
Effective medium theory for second-gradient elasticity with chirality
Grigor Nika, Adrian Muntean
We derive effective, parsimonious models from a heterogeneous second-gradient nonlinear elastic material taking into account chiral scale-size effects. Our classification of the ef…
Design and testing of 3D-printed micro-architectured polymer materials exhibiting a negative Poisson's ratio
Filippo Agnelli, Andrei Constantinescu, Grigor Nika
This work proposes the complete design cycle for several auxetic materials where the cycle consists of three steps (i) the design of the micro-architecture, (ii) the manufacturing…
Design of multi-layer materials using inverse homogenization and a level set method
Grigor Nika, Andrei Constantinescu
This work is concerned with the micro-architecture of multi-layer material that globally exhibits desired mechanical properties, for instance a negative apparent Poisson ratio. We…
Multiscale modeling of magnetorheological suspensions
Grigor Nika, Bogdan Vernescu
We develop a multiscale approach to describe the behavior of a suspension of solid magnetizable particles in a viscous non-conducting fluid in the presence of an externally applied…
