应变局部化问题是当前岩土力学研究的一个重要课题。处理应变局部化问题,一般的方法是引入正则化机制,包括黏性效应、Cosserat理论、非局部化、梯度理论。对应变局部化问题中的各种正则化机制应用进展作了系统总结,并分析讨论了各种正则化机制所存在的问题,最后对应变局部化问题中的正则化机制应用作了展望。
Strain localization is a very important subject in rock and soil mechanics. To deal with strain localization problems, some regularization mechanism must be introduced. The main regularization mechanism includes: viscosity effect, Cosserat theory, non-local theory and gradient theory. The development of these kinds of regularization mechanism in strain localization problems is summarized systematically; and the disadvantages of these regularization mechanism are analyzed and discussed. Finally, some primary ideas about the trends of regularization mechanism in strain localization problems are put forward.
