Abstract:When analyzing cavitation erosion, it is necessary to grasp the stress state inside a material due to the bubble collapse process. In this study, the behavior of a vapor bubble collapse and the stress distribution inside the material due to the bubble collapse were analyzed by using an in-house fluid/material coupled numerical method. In order to evaluate the stress inside the material, the "stress influence area" is introduced and used for the evaluation of the amount of input stress to the material. For anal… Show more
