Comparison of two anisotropic creep models at element level
Paper in proceedings, 2013

This paper presents a comparison of two anisotropic c reep models, ACM and Creep-SCLAY1, which differ in their formulation of creep strain rate. Creep is formulated in ACM using the concept of contours of constant volumetric creep strain rate, whereas the newly developed Creep-SCLAY1 model uses the concept of a constant rate of visco-plastic multiplier. The two mode ls are identical in the way the initial anisotropy and the evolution of anisotropy are simulated. A key assumption of both models is that there is no purely elastic domain. The models are compared at element level. The numeri cal simulations show that the Creep-SCLAY1 model is able to give a better representation of natural clay behaviour at element level.
