Modeling metamaterials by second-order rate-type constitutive relations between only the macroscopic stress and strain
VÃt Průša, Casey Rodriguez, Ladislav Trnka +1
We propose a thermodynamically based approach for constructing effective rate-type constitutive relations describing finite deformations of metamaterials. The effective constitutiv…

The conclusion that metamaterials could have negative mass is a consequence of improper constitutive characterisation
David Cichra, VÃt Průša, K. R. Rajagopal +2
The concept of "effective mass" is frequently used for the simplification of complex lumped parameter systems (discrete dynamical systems) as well as materials that have complicate…
