Answer
Stress relaxation tests are conducted by rapidly straining the material elastically in tension while holding the strain level constant and measuring the stress as a function of time.
For viscoelastic creep tests, a stress that is usually tensile is applied instantaneously and maintained constant while strain is measured as a function of time.
