ADVANCES IN NANOMECHANICS

概述在固态下纳米力学的若干研究内容．首先对纳米力学及其范畴进行界定,然后介绍纳米力学方法,包括属于纳观计算力学范畴的大规模分子动力学算法、连续介质/分子动力学交叠层算法、准连续介质算法和LMPM方法;及属于纳观实验力学范畴的纳米云纹法和纳米压痕法．随即阐述纳米力学的新兴研究领域:包括纳米晶体的超塑性变形、纳观断裂力学、纳米管力学和纳米压痕力学．

Several research thrusts in nanomechanics for solid state matters are reviewed in thispaper. The scope of nanomechanics is defined, and the methods are introduced. These methodsinclude nanoscopic computations (massive MD simulation, combined continuum/atomistic simu-lation, quasi-continuum simulation and LMPM) and nanoscopic experiments (nano-moire methodand nanoindentation). The emerging research areas in nanomechanics such as superplastic defor-mation of nano-crystalline materials, nanofracture, mechaincs for nanotubes and nanoindentationare briefiy described.
