Non-associated plasticity for soils

Aylin Ahadi, Steen Krenk

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceedingpeer-review


A brief overview is given of a non-associated plasticity theory
developed for soils based on the concept of a characteristic stress
state of vanishing incremental dilation, and a calibration
procedure using only test data from a standard triaxial test. The
capability of the model is illustrated by calibration examples and
predictions made for standard triaxial tests at different confining
stress levels and constant volume tests on sand. The model is found
to predict stress-strain behaviour and development of volumetric
strain well.
