报告题目: Mechanical Properties of Nanomaterials through Atomistic Simulations
报告人：Hanfei Zhan, Lecturer, Queensland University of Technology
Abstract. Nanotechnology has brought a grand development in a broad field of engineering in the past decades, which has enabled the design and manufacturing of devices/materials from the bottom, the inspections of observations/phenomena from the bottom. We’ve witnessed the increasing progression of additive manufacturing (e.g., 3D printing), the wide spread applications of high-performance composites and carbon fibers in replacing traditional metals/alloys to reduce the weight of machines, the increasing usage of renewable energy, and others. Focusing on the large-scale atomistic dynamics, this talk will discuss the intriguing mechanical properties of low-dimensional nanostructures (including 1D, 2D and 3D nanomaterials). Examples will be given to show how the continuum mechanics are adapted to describe the nanoscale mechanical behaviour [1-2], and how the thermal transport can be tailored at nanoscale [3-4]. Emphasis will then be put on the engineering applications and perspectives of nanostructures by taking carbon-based material as an example. Discussions will cover the failure behaviours of graphene under high-speed projectile, the application of diamond nanothread as reinforcement for polymers , the fiber interfacial properties , and other engineering applications. Some perspectives regarding the computational nanomechanics will be discussed.
