Taber Abrasion Tester Compression Stress Relaxation Equipment Ozone Test Chamber Foam Compression Tester Compression Stress .Rubber, vulcanized or thermoplastic — Determination of stress relaxation in compression — Part 1: Testing at constant temperature 5.1 When a constant strain is imposed on rubber, the force necessary to maintain that strain is not constant but decreases with time; this phenomenon is called force decay (stress relaxation). Conversely, when rubber is subjected to a constant stress, an increase in the deformation takes place in time; this behavior is called creep.
The simulated stress relaxation rate of the average contact stress on the upper surface of the rubber sealing gasket is 51.0%, and the stress relaxation rate of test results is 50.4%. The difference between them is 0.6%, which shows that the material parameters selected in this paper are reasonable, and the constitutive model can well simulate .Figure 2.
