In the oil and gas industry, one way of laying pipes on the seafloor is by thereeling process. In this process the pipe is subjected to a cyclic plastic deformation. Due tothis plastic deformation the mechanical properties of the material are changed. In thisstudy the finite element method is used to predict the influence of the cyclic plasticdeformations on the mechanical behaviour of the material. The fraction model is used todescribe the cyclic stress-strain behaviour. In order to be able to predict fracture of thematerial the Gurson-Tvergaard-Needleman damage model is used in conjunction with thefraction model. By comparing unit cell calculations with the damage model, the parametersq1 and q2 were determined for both the monotonic and cyclic loading conditions.
