| During the stress relaxation test, the sample is subjected to a rapidly applied strain which is then held for the remainder of the test. The relaxation behavior is studied by monitoring the steadily decreasing value of shear stress. This test is useful to obtain viscosity and initial modulus over the decay time. Moreover, for the frequency sweep tests, frequency ranges from 0.01 to 100 Hz were run at a low possible strain. |
