A structure-based constitutive equation for rubberlike networks (ABGIL), proposed in Part I is a combination of the connectivity term based on Langevin statistics (Arruda and Boyce, AB) and a constraint term which may be expressed in the form of the first invariant of the generalized deformation tensor (GI). The ABGIL equation was tested in Part II on networks of poly dimethylsiloxane) and styreneâbutadiene rubber. Parameters of the equation were obtained from the fitting procedure.
Konstitutivnà rovnice pro kauÄukovité sÃtÄ (ABGIL) založená na struktuÅe, která byla navržena v Äásti I, je spojenÃm Älenu daného konektivitou, založeného na langevinovské statistice, a Älenu daného prostorovými omezenÃmi, který je možno vyjádÅit ve tvaru prvnà invarianty generalizovaného deformaÄnÃho tenzoru (GI). Rovnice ABGIL je v Äásti II testována s použitÃm biaxiálnÃch experimentálnÃch údajů stanovených u sÃtà poly(dimethylsiloxanu) a butadienstyrenového kauÄuku. Porovnánà teorie s experimentem poskytlo parametry rovnice.
