Modelling large plastic deformations of cohesive soils using sequential limit analysis

Abstract:

This paper introduces sequential limit analysis (SLA) as a method for modelling large plastic deformations of purely cohesive materials such as undrained clay. The method involves solving a series of consecutive small-deformation plastic collapse problems using finite element limit analysis, thus ensuring high levels of accuracy, efficiency and robustness. The techniques needed to develop an SLA implementation for 2D (plane strain) problems are described in detail, including model geometry up...
