Abstract [en]

Modeling of the manufacturing process of high voltage power cables is performed with the aim of predicting residual stresses in the cable insulation. A viscoelastic power law type constitutive model is used which incorporates temperature and crystallinity dependence of the parameters. In this way the mechanical problem is coupled to the heat transfer and crystallization problems. In order to illustrate the effects of relaxation, a comparison to a thermo-elastic material model is made.
