Abstract

Abstract: This paper investigates the transverse contraction of amorphous bilayer 2D Silica with varying network heterogeneities under uniaxial tensile loading using athermal molecular simulations in LAMMPS. It turns out that the transverse contraction increases nonlinearly with the x ‐strain while it decreases with increasing network heterogeneity. We show that it is possible to engineer the heterogeneity of amorphous network materials, making them potential candidates for nano‐electromechanical applications.
