Elasto-plastic anisotropic hardening model for sand in a wide stress region

H. Murata, N. Yasufuku

Research output: Chapter in Book/Report/Conference proceedingChapter


The elasto-plastic constitutive model, taking account of anisotropy effects induced by the initial consolidation and the following shear processes, is established in order to describe the stress-strain behavior of an anisotropically consolidated sand in a wide stress region. The proposed model consists of a set of the yield function, plastic potential and hardening modulus which are expressed based on the theoritical considerations and experimental evidences. The resultant equations are not only a simple form enough for use but also can give good qualitative predictions for the axisymmetric triaxial test results of sand.
