Über dieses Buch

This book addresses several important issues concerning the nanomechanics of graphene, an area that is vital to a fundamental understanding of graphene deformation, and to the design of graphene-related materials. The content chiefly focuses on the out-of-plane mechanical behaviors of graphene, and their effects on the mechanical properties of graphene composites. In addition, the book puts forward original theoretical mechanical models based on continuum mechanics, discontinuous effects and atomistic simulations. The findings presented here can provide the basis for valuable guidelines on the design and application of graphene and graphene composites in the field of nanomechanics.

Chapter 1. Introduction
Abstract
Graphene was first separated from graphite by Geim et al. using an adhesive tape in 2004 [1, 2]. It is a two-dimensional (2D) material with a single layer of carbon atoms arranged in a hexagonal lattice, and opens up a new era of 2D materials.

Chapter 2. Multiscale Methods to Investigate Mechanical Properties of Graphene
Abstract
This chapter begins with a brief review of the common methods for studying the mechanical properties of graphene and its composites, and then introduces the molecular dynamics method and the first-principle calculations used in this thesis. A method of converting physical quantities from molecular simulations to continuum models is explained. Some C++ codes for simulation and modeling in this thesis are introduced.

Chapter 3. Buckling of Graphene Monolayer Under In-Plane Compression
Abstract
For graphene monolayer, the out-of-plane induced by in-plane loading is buckling, which is one of the basic out-of-plane deformations raised in Chap. 1. The static and dynamic buckling of graphene monolayer is studied by theoretical mechanical models and numerous simulations in this chapter.

Chapter 4. Dynamic Ripples in Graphene Monolayer
Abstract
The dynamic ripples in graphene monolayer are one of the important out-of-plane mechanical behaviors of graphene, which are generally motivated by out-of-plane loading. Their deformation mechanism and potential applications are discussed in this chapter.

Chapter 5. Defect-Induced Discontinuous Effects in Graphene Nanoribbon Under Torsion Loading
Abstract
Defects are ubiquitous in graphene monolayer, which are considered as the foundation of the design of graphene and graphene composites. In addition, defects may induce discontinuous effects for the mechanical behaviors of graphene. In this chapter, the defect technology of graphene is reviewed and discussed. The mechanical behaviors of graphene nanoribbon under torsion loading, which is a representative case including both the static and dynamic out-of-plane deformation, is analyzed to reveal the discontinuous effects induced by defects.

Chapter 6. Mechanical Behaviors of Graphene Nanolayered Composites
Abstract
Graphene/matrix interface plays a dominant role in the mechanical properties of graphene composites. Based on the understanding of out-of-plane mechanical behaviors raised in previous chapters, the mechanical properties of graphene nanolayered composites are studied under two representative loads: out-of-plane shock and in-plane shear. The effects of graphene interfaces on the mechanical properties are studied, which is important for the design of graphene composites.

Chapter 7. Summary and Future Work
Abstract
A summary of this thesis is presented, along with main conclusions on the basic out-of-plane mechanical properties of graphene and mechanical behaviours of graphene composites. The novelty of the research conducted in this thesis is addressed. In addition, remaining issues for the design of graphene and graphene composites are discussed, which may provide some useful guidance for engineering applications in the field of nanomechanics.
