Abstract    The prediction of the response of geotechnical structures under cyclic loading is difficult. Numerically, such a prediction proves problematic because even small systematic errors of constitutive models are quickly accumulated. Our objective is the prediction of the response of geotechnical constructions under cyclic loading with a large number ( ) of cycles by using an explicit approach for this purpose. The formulation of this model is based on numerous cyclic tests drained. The reliability of model is tested with experimental values. Good correlation exists between predicted and experimental response.The second section is devoted to the parametric study of the proposed formulation. We are essentially interested in the influence of the cyclic parameters on the evolution of the accumulated irreversible strain.
