At strains below the yield point, all strain is considered to be elastic and EF = 1.
Yeoh's (ref 5) proposed cubic equation in the invariant ([I.sub.1] - 3) as the strain energy function is a good approximation of the characteristics of carbon black filled rubber compounds, especially at strains less than 80% where radial tires normally operate.
Most of the raw synthetic elastomers tested showed linear viscoelastic behavior at strains under [+ or -]14% strain (1 degree arc).
