Graphene shear modulus
WebDownload scientific diagram Young's modulus, bulk modulus and shear modulus of SiC-graphene composites as obtained by A) Voigt and B) Hill approximation. C) Poisson's … WebApr 13, 2024 · The shear modulus of this composite differs substantially as a function of the shear direction. When shearing causes the graphene oxide sheets to compress, they buckle; however, when they are sheared in the other direction, they are stretched. This asymmetry can convert symmetric vibrations into asymmetric motion.
