| Abstract: | 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... |
