WebThis approach was explicitly proposed by Medalia who adapted the Guth, Gold and Simha equation to modulus (see Equation 5.12), but the effects of CB on mechanical properties are more or less complicated depending on the grade and level of CB and, moreover, one cannot expect much from considerations solely based on hydrodynamic effects. [Pg.150 ... WebNov 21, 2024 · This factor was determined by comparing the stress–strain behaviors of unfilled and filled rubbers. Guth and Gold [13, 14] have addressed the impact of filler content on the small strain modulus of a rubbery matrix. The Guth–Gold equation, which is typically applied for filler volume fractions below 35% (\(\varphi 35\%\)), is given as follows:
