Ebook: An Extension of the Governing Principle of Dissipative Processes to Nonlinear Constitutive Equations

Scientific article. — Annalen der Physik (7 Folge), 1983, Bd. 40, H. 4/5, S. 189–193.A generalisatipn of Onsager’e reciprocal relations has been proved by phenomenological methods. It is pointed out that Gyarmati’s variational principle is valid in case of nonlinear constitutive equations, too.
