Analysis on Parameters in Duncan-Chang Constitutive Model
Duncan—Chang constitutive model is widely used for it reflecting the main property—nonlinearity of soil. In the paper, the geotechnical Duncan—Chang constitutive model is introduced into ANSYS software by using the User Programmable Features (UPFS) of ANSYS. The calculation results with eight parameters variation in Duncan—Chang model are analyzed, which has much wider reference value for geotechnical engineering problems. The relative solution methods provide important reference for other constitutive models to be introduced into and analyzed in ANSYS program.
