The method to predict wear depth and wear volume of tube at near-distant future from measured or prescribed depth at present time

摘要

The existing results of the impact model for a cylindrical projectile are modified. The material constant associated with the impact model is inversely determined from the given wear depth and number of impacts. The wear depth or wear volume in the near-distant future is estimated from the material constant using the present wear status. The results are compared with measured depths of a steam generator tube in a nuclear power plant. The results show that predicted wear depth envelops the measured depth. It can be concluded that the methods employed in the present paper can be applied to the prediction of wear depth from a given status of wear at the present time.
