Abstrakt: This paper describes a new numerical method – within an ANSYS Workbench finite element method environment – for simulating the kinetics of the Heat Build-up process in rubber under cyclic multiaxial loading. A novel measuring setup controls a multiaxial load which forces the heat build-up by combining the dynamic alteration torque and multi-planar bending. In this method, the experimentally determined Heat Build-up is calculated numerically from the strain energy density with the determined hyperelastic material parameters at room temperature. A new quantity, the so-called dissipation constant, is introduced which makes it possible to determine the dissipation energy of cyclically loaded specimen. The experiments and calculations were carried out for a broad range of loading conditions, varying in both bending angle and rotational speed. Finally, the agreement between the experimentally determined and the calculated data is discussed. [ABSTRACT FROM AUTHOR]
