Comparison of Anisotropic Rate-Dependent Models at Element Level

摘要：

　　Two recently proposed anisotropic rate-dependent models,EVP SCLAY1 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 onnumerical 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.
