Dynamic behavior of graphene-origami-based meta-auxetic doublet nanobeam with memory-dependent effect

Abstract This work explores the mechanical characteristics response electro-magneto-thermoelastic (EMT) nanobeams by simultaneously accounting for fractional viscoelasticity, nonlocal elastic interactions, doublet mechanics, and couple-stress effects. A meta-auxetic architecture is integrated into the nanobeam inspired by graphene-based origami structures, allowing its mechanical behavior to be tuned through geometric reconfiguration and engineered microstructural features.
