What is it about?

If a rubber band is subjected to a constant force, its length will increase with time. This phenomenon is called creep. If a rubber band is in tension under a fixed deformation, the force in the band will decrease with time. This phenomenon is called relaxation. Both the creep and the relaxation are the time-dependent response. The proposed model can predict the response.

Why is it important?

The current methods developed for rubber creep and relaxation are validated to a specific environment. By combination with previous work on temperature effect, the model with general capabilities has been established and can be used to predict time-dependent response of different rubber components under different loadings, hardness, temperature (combined with the previous work).


This methodology can save significant cost and time in engineering design and applications, even a new product is in a design stage.
