Summary

Internal cyclic loading of a viscoelastic hollow sphere is considered. The influence of the material properties in dilatation and shear on the heat generation and temperature distribution is analysed.

For common polymeric materials the elastic and viscoelastic dilatational properties are found to be of less improtance than the temperature dependence in shear.

Zusammenfassung

Betrachtet wird eine viskoelastische Hohlkugel unter zyklischem Innendruck. Der Einfluß der Materialeigenschaften in Dilatation und Schub auf Wärmeentwicklung und Temperaturverteilung wird untersucht. Es zeigt sich, daß für gewöhnliche Polymere die elastischen und viskoelastischen Materialeigenschaften bei Dilatation von geringerer Bedeutung als die Temperaturabhängigkeit der Materialeigenschaften bei Schub sind.
