WebIntroduction. In this chapter we build a general but simple elastic-plastic model of soil behaviour, starting with the experimental observation of the existence of yield loci that was discussed in Chapter 3. Other features are added as necessary, and their selection is aided sometimes by our knowledge of well-known characteristics of soil ...
