Abstract
ABSTRACT In this paper, a tool for better controlling the use of constitutive models in numerical methods in geotechnical engineering is proposed. For this purpose a constitutive model based on CJS model is developed. This model is hierarchically composed of several levels of constitutive modelling, respectively from a simple level to a more complex level. The transition from one level to another is easy in operating only over some constants of the model. The strategy of identification and physical meanings for all of the constants are clearly defined. In order to validate the different levels of the model, the results of homogeneous drained and undrained tests, in the same way as boundary problems concerning pressuremeter and tunnel are presented and discussed.
