Abstract

A three-dimensional cone is established by adopting the critical soil mechanics and the membership function to the bounding surface model to express the dynamic characteristics of the rock-soil materials under loading-unloading; The new axis of the cone expresses the plastic membership function of stress, in which the loading surface corresponds with the membership function; The fuzzy hardening modulus of the loading surface is obtained from that of the boundary surface , the plastic flow criteria are fixed by the membership function; The model can well express the accumulated plastic strain; The model parameters are obtained from dynamic triaxial experiment, and the numerical results obtained from finite element method correspond with the experimental results, proving the model is valuable.
