Both models distinguish between loading and unloading regimes in which a modulus function is used in the loading case, whereas in the unloading part, the modulus is constant and its value is that at which a switch from loading to unloading occurs.

All the constants and modulus functions can be obtained from the experimental data of the stepped creep and recovery tests (Fig.

Consider the kernel r associated with the modulus function M and let

mn], then any modulus function f and a non-negative RH-regular summability matrix method A, then [[chi].

If a modulus function f is eventually concave then [d.

As mentioned in the introduction, in this section we will generalize the results in [11], which can be retrieved by considering in our results the modulus function f(x) = x.

If convexity of Orlicz function M is replaced by subadditivity of M, then this function is called

modulus function, defined by Nakano [15] and further discussed by Ruckle [19] and Maddox [11] and many others.

Once linearized, the

modulus functions of shear and elongation should agree with a factor of three, and it is indeed the case, except for rubbers that exhibit strain-induced crystallization and strain-induced association (refs.
