On the generalised stretch function
Original language description
The tube theory represents a powerful tool for the description of polymer behaviour. In this theory, the term in the form of an integral over a full solid angle of a magnitude of deformed unit vector represents the stretch function. This term relates thelengths of the random walk of a molecule in deformed and undeformed states. For the case of the Doi-Edwards model, the integrand is raised to a power of one, however, for other models the power differs from one. The aim of this contribution is to derivean analytical algebraic approximation of a general form of this integral with the integrand raised to an arbitrary power within the physically justified interval between zero and two.
