Abstract: In applying the elastic shell models to monolayer or fewlayer twodimensional (2D) materials, an effective thickness has to be defined to capture their tensile and outofplane mechanical behaviors. This thinshell thickness ...

Abstract: Poisson’s ratios of diamond-like structures, such as cubic C, Si, and Ge, have been widely explored because of their potential applications in solid-state devices. However, the theoretical bounds on the Poisson’s ratios ...

Abstract: Abstract. Materials exhibiting near-zero transverse deformation under tension, a property known as an ultralow Poisson's ratio (UPR), are highly sought for precision applications. However, UPR materials are conventionally ...

Abstract: Multilayer graphene exhibits strong mechanical anisotropy in the nonlinear elastic regime, and tuning this mechanical anisotropy without damaging the graphene is a tough challenge. In this work, we propose an efficient ...
