CMMI ? 0926851: Nonlinear Mechanics of Graphene-Based MaterialsPI: Rui Huang, University of Texas at AustinAbstract:This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The objective of this project is to develop a theoretical framework for monolayer graphene based on nonlinear continuum mechanics and atomistic modeling. Within the framework, the fundamental mechanical properties of monolayer graphene and its derivatives will be systematically studied. First, a nonlinear continuum theory will be developed for two-dimensional sheets under arbitrary deformation in the three-dimensional space. Next, atomistic modeling approaches will be developed to simulate and deduce the fundamental mechanical properties of monolayer graphene. The continuum theory and atomistic modeling methodology will then be combined to study carbon nanotubes and graphene nanoribbons as two basic forms of graphene-based materials. Finally, integrated graphene structures with graphene monolayers interacting with supporting substrates will be investigated.With a wealth of exceptional physical properties, graphene holds great promises for a variety of applications, including graphene-based composite materials, nanoelectronics and electromechanical resonators. The research on mechanical properties of graphene will complement the already abundant research activities in material science and condensed-matter physics that have largely focused on its electronic properties. It is envisioned that fundamental understanding of the mechanics of graphene-based materials will open new perspectives for both fundamental physics and practical applications. In addition, education and outreach activities will be incorporated within the proposed project to enhance its societal impacts.

CMMI？0926851：石墨烯基材料的非线性力学PI：Rui Huang，德克萨斯大学奥斯汀分校摘要：该奖项根据2009年美国复苏和再投资法案（公法111-5）资助。本计画的目标是建立一个以非线性连续介质力学和原子模型为基础的单层石墨烯的理论架构。在此框架下，将系统地研究单层石墨烯及其衍生物的基本力学性质。首先，将发展一个二维薄板在三维空间中任意变形的非线性连续理论。接下来，将开发原子建模方法来模拟和推导单层石墨烯的基本力学性能。然后，将连续介质理论和原子建模方法相结合，研究碳纳米管和石墨烯纳米带作为石墨烯基材料的两种基本形式。最后，石墨烯单分子层与支撑衬底相互作用的集成石墨烯结构将被研究。石墨烯具有丰富的特殊物理性质，在各种应用中具有巨大的潜力，包括石墨烯基复合材料，纳米电子和机电谐振器。对石墨烯力学性质的研究将补充材料科学和凝聚态物理学中已经丰富的研究活动，这些研究活动主要集中在其电子性质上。据设想，对石墨烯基材料力学的基本理解将为基础物理和实际应用开辟新的视角。此外，教育和外联活动将纳入拟议项目，以加强其社会影响。
