Graphene frontier theory of mechanics

Source: 2020 - 03 - 28 for hits: mechanical frontier of graphene graphene due to its historic breakthrough in the study of physical properties and has been widely concerned. Starting from the use of different environment, different areas of research reveals that the graphene may have many good features, and application and the future of the performance of these high expectations. In terms of mechanical performance, complete the graphene layers of tensile strength of more than two orders of magnitude higher than the existing engineering data. At the same time, our intuition tells us that single atomic structure deformation data is easy to produce the membrane surface. In addition, the large scale preparation of graphene inevitable tend to make its inherent defects. Understand these unique space limitations brought by the mechanical behavior and the new structure and its difference from the 3 d data, and to establish a new system analysis method and theory to describe the deformation behavior, is the key to dealing with graphene data reliability and durability in the course of engineering use. Recently, 'national science about mechanics, Chinese Academy of Sciences research published in the state key laboratory of nonlinear mechanics discussion part of sanitary ware, mechanical engineering at the university of Colorado, Byrd ronggui professor Yang overview jointly compiled articles' graphene Nanomechanics' ( The 2018 Sci pastor, doi: 10. 1093 / nsr / nwy067。 http: / /dx. doi。 org/10. 1093 / nsr / nwy067) 。 Added other functions overview of all aspects in this paper, we introduce the graphene, this article from the basic mechanics of two-dimensional crystal structure to describe methods, an overview of the current scope of graphene deformation mechanics, strength and cracking, and basal information interaction between the operating theory, and discusses the mechanical aspects of the theory of several problems to be further discussed. Consider graphene as the most typical representative of the significance of two-dimensional data, mechanical theory is included in the study can be used to provide mechanical study other two-dimensional data, even can be directly used to describe the mechanical behavior of the other data.
