Abstract

This paper addresses the modeling of complex rheological media possessing both inertial and viscoelastic properties. In the study, a three-phase hybrid model consisting of an elastic spring, a viscous dashpot, and an inertial mass is constructed, and a differential equation relating stress and strain is derived. Furthermore, the temperature dependence of the viscosity parameter is analyzed based on the Arrhenius and VFT equations. The model enables an accurate evaluation of the temperature factor's effect on the damping coefficient in rheological processes.
