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).

Perspectives

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