Abstract

Two recently proposed anisotropic rate-dependent models, EVPSCLAY1 and ACM are used to simulate the stress-strain behaviour of Vanttila clay. The models are identical in the way the evolution of anisotropy is simulated, but differ the in way the rate-effects are taken into account. Based on numerical simulations against element level tests, using objective parameters, suggest that EVP-SCLAY1 is able to give a better representation of the clay response at element tests than ACM in 1D loading, but the latter gives a better prediction for undrained strength.
