Implementation of generalized viscoelastic material model in abaqus code
An accurate description of behavior of bituminous mixes is necessary to adequately predict and evaluate the time dependent characteristics and the evolution of pavement distress. The generalized Maxwell model, currently considered to be one of the most suitable to characterize mechanical behavior of viscoelastic materials and widely used in many commercial FEM codes, is presented. A Prony series expansion implemented in ABAQUS code, is used to express the material’s behavior. The theoretical background of the model is briefly discussed. Finally, the model was efficiently used for numerical simulation of stress relaxation experiment.
