Nonlinear viscoelastic oscillations of a vehicle in vertical direction excited by static imbalance are considered. When taking into account the rheological properties suspension material and spring, Boltzmann-Volterra principle was used. Mathematical models problem under consideration obtained, which described systems nonlinear integro-differential equations. A solution method based on quadratu...

Minimally invasive experimental methods that can measure local rate dependent mechanical properties are essential in understanding the behaviour of soft and biological materials a wide range applications. Needle based measurement techniques such as Cavitation Rheology Volume Controlled Cavity Expansion (VCCE), allow for minimally testing, but have been limited to measuring elastic material prop...

The nonlinear mechanical behavior of viscoelastic materials is modeled based on the Schapery integral model containing internal variables. In this context, a new approach for strain-dependent material properties introduced considering one-dimensional formulation with functions an oscillatory load case. addition to storage and loss modulus, higher order harmonic oscillations in stress response a...
