Abstract

Physical and chemical properties of 2D material are highly sensitive to its structures whose regularity are seldom investigated, here we proposed a simple mechanical model whose covalent bonds are connected by angle springs, with which we gave insight into stability, bending stiffness and some other properties of 2D structures. It is found that Flat, Chair and Washboard possess larger existent possibilities, which are consistent with existing 2D materials' structures. This model is a tool to evaluate existent possibilities of periodic 2D structures from mechanical viewpoint.
