ASSOCIATED AND NON-ASSOCIATED VISCO-PLASTICITY AND PLASTICITY IN SOIL MECHANICS

The visco-plastic model is established as a realistic general description of soil behaviour as well as A computationally convenient fiction for solving any properly formulated plasticity problem. The paper focuses attention on simple elastic-ideally plastic formulations in which both associated and non-associated forms of behaviour are assumed. In the non-associated form the usual bounding theorems are not applicable and it is of interest that in some cases collapse situations significantly different from those given by limit theorems are predicted. Also, some problems of strain-dependent plasticity are solved to demonstrate the flexibility of the visco-plastic algorithm. (A). /TRRL/
