Description
Summary:Material property models for poly(etheretherketone) (PEEK) have been combined with a residual stress model to provide a means for investigating the effect of crystallization process on the residual stress development in semicrystalline materials. The analysis shows that crystallization causes an increase in the residual stress levels. This increase is affected through an increase in the resin modulus values and through the resin modulus build‐up at higher temperatures. The shrinkage due to crystallization was found to have no effect on the residual stress development in neat PEEK.
