纳米压痕技术是一门在微观尺度上测量材料力学性能的新兴技术,分子动力学模拟则可对抛光、超声振动、激光加工等工艺过程进行仿真,在研究加工过程中材料受微观粒子挤压、划擦及冲击等而变化的力学性能机理方面具有显著优势,故总结了分子动力学模拟和纳米压痕技术的基本原理,对采用分子动力学模拟研究纳米压痕技术的现状进行了综述.两种先进技术的有机结合,将极大地促进材料在微观尺度下的研究进程.
Research Progress of Nanoindentation Technology Based on Molecular Dynamics Simulation
Nanoindentation technology is an emerging technology to measure the mechanical properties of materials at the microscopic scale,and molecular dynamics simulation can simulate the processes of polishing,ultrasonic vibration,laser processing,etc.,which has significant advantages for studying the mechanical properties of materials changed by the extrusion,scratching and impact of microscopic particles during processing.Therefore,the basic principles of molecular dynamics simulation and nanoindentation technology are summarized,and the current status of nanoindentation using molecular dynamics simulation is reviewed.The organic combination of the two advanced technologies will greatly promote the research process of materials at the microscopic scale.
