PHENOMENOLOGICAL MAPPING METHOD AND MATHEMATICAL ANALOGY OF HYBRID
SYSTEM DYNAMICS
Importance of phenomenological mapping and mathematical analogy
increase with knowledge of numerous rare and unique phenomena in
different kinds of hybrid system dynamics. Phenomenological mapping
and mathematical analogy between multi pendulum systems, sandwich
multi plate systems, sandwich multi beam systems as well as axially
moving multi belt systems and mechanical chains with different
coupling by standard light elements ? elastic, hereditary or creep
properties expressed by differential, integral, or fractional order
differential operators are considered. Also, for homogeneous hybrid
listed systems, the corresponding characteristic equations and
solutions are obtained with corresponding periodic, as well as
rheolinear modes in analytical as well as in graphical forms.
Construction of Analytical dynamics of the hereditary discrete system
by Goroshko and Hedrih and also Analytical dynamics of the creep
discrete systems with standard light creep elements with constitutive
relation expressed by fractional order derivative, open an analogy
between these systems and systems in automatic control.

CLASSICAL AND RATIONAL VERSUS EXTENDED THERMODYNAMICS OF
INELASTICITY
Some classical contributions to irreversible thermodynamics like ([Caratheodory, 1909, Born, 1949; Prigogine, 1955, Meixner, 1976]) are very precious and deserve a careful attention. They are shortly reviewed. Then rational thermodynamics of Coleman and Noll, 1963 is presented. Extended thermodynamics of Ingo Muller, 1972, applied to inelasticity, is also shown. Finally, some highlights of endochronic thermodynamics (Vakulenko, 1970, Fomin, 1975) with its extension to quasi rate-independent viscoplastic materials (Micunovic, 2005) based on plastic delay (Rabotnov, 1980) are given.
Sednice se održavaju u zgradi SANU, Knez Mihailova 35, u sali 2 na prvom
spratu.
