ABSTRACT

Here it is shown in a finite element context, using the overlay method, how different dynamic stiffness and loss values in the elements of the

1 INTRODUCTION

The dynamic stiffness and loss angle of elastomers increases with higher filler content. Fillers can also introduce a non-linear dynamic behavior shown as an amplitude dependence of the dynamic stiffness and loss angle. Although it is a bit inappropriate the linear viscoelastic stiffness and loss measures are used also for the non-linear dynamics of filled rubbers.
