On the long-term deformation process in viscoelastic composites around an elliptical hole.

This paper deals with the dependence of stress redistribution around an elliptical hole in a composite on viscoelastic properties of the composite components. The results are obtained for composites with elastic and viscoelastic reinforcement. It is shown that the stress on a surface of the hole can change non-monotonically for the case of viscoelastic reinforcement, i.e., there can be maxima on the stress-time diagrams during the lifetime of the composite.
