摘要
主要讨论了三种将连续介质力学和微/纳观理论相结合而发展起来的方法:多尺度连续介质方法、连续介质—分子动力学耦合方法和准连续介质方法。介绍了三种方法的基本思想、基本原理和研究进展。讨论了三类多尺度方法的适用范围,展望了多尺度方法未来的发展趋势。
Three multiscale approaches which combined continuum mechanics with micro/nanoscale technology were introduced;multiscale continuum method, continuum-molecular coupling method, quasicontinuum method.The basic principles, formulas and recent developments of these approaches were reviewed. Finally,how to use the three multiscale methods in an appropriate micro/nano-scale range was discussedand the recent development tendency was outlined.
