Prediction of residual stresses in cross-linked polyethylene cable insulation
2005 (English)In: Polymer Engineering and Science, ISSN 0032-3888, E-ISSN 1548-2634, Vol. 45, no 8, 1132-1139 p.Article in journal (Refereed) Published
Modeling of the manufacturing process of high-voltage power cables was performed with the aim of predicting residual stresses in the cable insulation. A viscoelastic power law-type constitutive model was 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 thermoelastic material model is made.
