Elastoplastic Simulation of the Cyclic Undrained Behaviour of Soft Clays

According to cyclic displacement behaviour of soft clays,the incremental elatoplastic model is developed using the anistropic hardening modulus field theory. The method determinging parameters of the model in cyclictriaxial tests is studied. The results predicted by the model shaw that cyclic undrained stress-strain relation of softclays can be fairly simulated by the model.
