Abstract
Full-scale experiments in biharmonic uniaxial loading of low-modulus highly filled viscoelastic polymer-based composites were performed, and the hysteresis of the dynamic elastic modulus was obtained by changing the low-frequency component of the biharmonic loading. The effect of amplitude of the high-frequency component of the biharmonic loading law on the dynamic mechanical properties of the viscoelastic low-modulus composites is investigated. Relationships for the dynamic modulus and the loss angle at different parameters of the biharmonic loading law are found.
