Relaxation and creep compliance curves generated form this test are useful for determining a material's behavior over a long period of loading. Many times this test can generate data that can predict material behavior out to time periods that are not feasible to test any other way. This data can also be used in simulation software to predict long term behavior. If you wish to have data provided for simulation software, please select the appropriate software vendor and viscoelastic model in the TestPak section.
