Elastomers and natural rubbers exhibit complex responses to mechanical loading, and accurately capturing that data for simulation requires accurate test data. Veryst has extensive experience developing and executing test plans for natural and synthetic rubbers. Some of our most recommended test procedures are listed below. Veryst can also recommend an appropriate combination of test program and material model if you are unsure of what test program is required for your application.
Note that all the tests below can be performed at reduced or elevated temperatures. We recommend 3-5 repeats for each strain rate and temperature combination.
|program Id||Description||Suitable for characterizing and Modeling|
