Abstract:

Mechanical behavior of large-scale deformation for rubber stress cone of high voltage cable accessories was studied with a German Zwick020 material test machine. Stressstrain relation curves were obtained under different temperatures and different loading rates. From these curves, influences of temperature and loading rate were analyzed. The material’s mechanical properties were theoretically analyzed with the Mooney-Rivlin model, and some fitting parameters of the material were got from experimental data. Two constitutive equations of material were then constructed, and the stress obtained in the experiment was compared with theoretical calculation. It shows that the equations are suitable in engineering practice and can be used for further research.

Key words: rubber; stress cone; constitutive relation; tensile test
