Odd Elasticity in Strain-Gradient Continua: Anisotropy Classification and Non-Hermitian Elastodynamics
Payam Poorsolhjouy
Odd elasticity extends continuum mechanics to active nonconservative systems containing internal energy sources, such as robotic active metamaterials with nonreciprocal feedback. M…
Neural Operator Representation of Granular Micromechanics-based Failure Envelope
Jinkyo Han, Payam Poorsolhjouy, Bahador Bahmani
Micromechanics-based granular models are widely used to predict the failure behavior of porous and particulate materials, including concrete, soils, foams, and biological tissues.…
Connecting discrete particle mechanics to continuum granular micromechanics: Anisotropic continuum properties under compaction
Payam Poorsolhjouy, Marcial Gonzalez
A systematic and mechanistic connection between granular materials' macroscopic and grain level behaviors is developed for monodisperse systems of spherical elastic particles under…
Statistical characterization of microstructure evolution during compaction of granular systems composed of spheres with hardening plastic behavior
Marcial Gonzalez, Payam Poorsolhjouy, Alexander Thomas +2
An extensive numerical campaign of particle mechanics calculations that predict microstructure formation and evolution during die compaction, up to relative densities close to one,…
