Abstract:
The study of static contact between cylinder and plane has been extensively investigated
for the contact pressure and deformation of plate in contact zone using Hertz theory [1].
However, dynamic consideration that involves mathematical complexity including the
effects of rotating speed and time dependent material property is more appropriate for
biomechanic materials. In this study the simulation of viscoelastic material was
undertaken to determine the effects of rotating speed and material behavior on the
deformation of viscoelastic plate in comparison with the behavior of an elastic material
using the finite element method. It was found that, for a constant loading, the
deformation of elastic meterial would reach a certain value over a period of time, while
the deformation of viscoelastic material increased dramatically with time. Moreover, it
was found that the rotating speed had an influence on the material deformation but only
a linear relationship was noted.
