Localization Analysis of a Saturated Elastic Plastic Porous Medium Based on Regularized Discontinuity

摘要

In the present paper we analyze the conditions for band-shaped localization to occur in the hydro-mechanically coupled problem. In the localization analysis, the concept of regularized discontinuity is used at the application to the conservation laws of momentum and mass. As a result, we obtain a coupled localization condition, where the situation of partly drainded conditions is discussed and compared to the extreme cases of fully drained and undrained situations.
