Abstract

A hypoplastic constrtutive model was presented and the determination of its parameters hs and n was investigated.According to the hypoplasticity and optimization,an improved method to determine the parameters of n and hs using iterative operation was put forward.It was shown that the present method could be used to determine the parameters of hypoplashc constitutive model.
