In this study, molecular dynamics (MD) is used to simulate adhesive wear, where the simulation model is simplified as a single α-Fe (bcc material) under shear deformation. The adhesive plane is assumed to be the (001) plane and the slip(shear)direction, the [010] direction. First, MD analysis is carried out with/without periodic boundary conditions in the [100] and [010] directions to clarify the influence of periodic boundary condition. Next, the shear deformation speed is varied and its influence on the behavior of adhesive wear is examined. The results are summarized as follows: (a) The periodic boundary condition significantly affects the deformation of adhesive wear. That is, the existence of free boundary plays a very important role in wear. (b) The deformation speed does not affect the type of structural destruction of adhesive wear, and only the time from the start of shear deformation to the beginning of adhesive wear becomes short as the deformation speed becomes high.
