摘要

本研究的重点是通过分子动力学模拟,研究最近发现的一种二维碳同素异构体(称为平面网状τ)的力学性能。平面网-τ是一种独特的、尚未探索的碳构型,因其碳原子在平面晶格中排列成错综复杂的网络而闻名。这项研究旨在加深对平面网τ机械特性的了解。这包括研究杨氏模量、断裂应变、极限强度、极限应力下的应变以及应力-应变曲线等参数。本研究通过有意操纵变量(如引入空位缺陷、改变温度和调整尺寸)来实现这一目标。二维碳同素异形体中的空位缺陷会严重损害其机械性能,降低刚度并增加机械故障。尺寸的变化会通过收缩进一步影响这些特性,从而影响强度和弹性。这些结果凸显了这些结构的各向异性。

Molecular dynamics investigation on the mechanical properties of a novel 2D carbon allotrope: Planar net-τ nanoribbon
This study is focused on investigating of the mechanical properties of a recently discovered two-dimensional carbon allotrope, known as planar net-τ, through molecular dynamics simulations. The planar net-τ is a unique and unexplored carbon configuration known for its intricate network of carbon atoms arranged in a planar lattice. The study aims to improve understanding of the mechanical properties of planar net-τ. This includes investigating parameters such as Young's modulus, fracture strain, ultimate strength, strain at ultimate stress, and the stress-strain curve. This study achieves this by deliberately manipulating of variables, such as introduction of vacancy defects, altering temperature, and dimensional adjustments. Vacancy defects in 2D carbon allotropes significantly impair their mechanical properties, reducing stiffness and increasing mechanical failure. Changes in dimensions further impact these properties through contraction, affecting strength and elasticity. These results highlight the anisotropic nature of these structures.
