Wavy patterns of stress and temperature distribution are occasionally observed along the circumference of a rotating viscoelastic disk under a contact load. This phenomenon is caused by a combination of physical and mechanical features such as dynamic behavior, heat generation due to loss energy, heat conduction and various modes of vibrations in the viscoelastic disk including the loading system. This study attempts to give a rational explanation of the phenomenon, through experimental and theoretical approaches, by means of dynamic modeling of the entire vibrating system. The study by means of dynamic analysis revealed that the wavy stress pattern results from the resonant vibration of the loading mechanism which corresponded to its natural frequency. It is emphasized that the peculiar vibration is strongly influenced by temperature-dependent dynamic properties of the viscoelastic disk.
