The origin of Classical Rheology
The fundamental presentation for modern rheology is discussed by Malkin and Isayev*:
“The complete review of the theory of linear viscoelasticity was summarized Bernhard Gross:
Mathematical structure of the theories of viscoelasticity, Hermann & Cie, Paris (1953).
He called his approach ”dogmatic” because it was based on some fundamental principles and it
appeared possible to present the theory in a compact and clear form.”
* A Ya. Malkin, A. I. Isayev: Rheology: Concepts, Methods & Applications, ChemTec Publishing, Toronto, 2006.
Gross noticed that the formalism of dielectric and viscoelastic relaxations are identical. He wrote a rheologial book discussed above.
We proved now on these pages that macromolecules do not behave exatly similar way
as classical dielectric phenomena.
High valuated Ferry, Tschoegl and others had only done continuum of “dogmatic” works for the review by Gross.
Who was this forgotten
great scientist Bernhard Gross?
I bought the last single book recently available (found from the past Aerojet library, Sacramento, California
Space rocket manufacturer). Due to immaterial rights I copy only few pages found attached as a sample of book:
"Mathematical structure of the theories of viscoelasticity"
As a summary our works based on control theory are as “dogmatic” as classical presented earlier by Gross.
