3) are necessary: pressure, temperature, compressibility, the universal gas constant
, and molecular weight.
An alternative approach is to assume that the temperature dependence can be represented by an Arrhenius equation from which an activation energy can be calculated, t = A exp (E/RT) where A is a constant, E is the activation energy, R is the gas constant
, and T is the cure temperature in degrees kelvin.
Where R is the gas constant
, T absolute temperature in Kelvins, F is Farraday constant, and [a.
where [Sigma] is the Cauchy stress, B the Finger strain (or left Cauchy-Green strain tensor), 1 the unity tensor, R the gas constant
, T the absolute temperature, V the molar volume and [p.
