Abstract:
ABSTRACT
Shot-peening process modeling has been a challenging task because of the complexity of the process. It is extremely time consuming to model individual shots in FE model in
presence of contact and subsequently keep track of such shots. Discrete element method has evolved over the years and now commercially available software can be used to
model individual shots and overall shot-peening process. However, major limitation of the current DEM based approach is that the method considers work piece material to be
elastic only and thus is not able to explicitly model plastic deformation and residual stresses induced by shot-peening. A novel approach is proposed where; one can take
spatial information of force vs. time from DEM solution and solve a transient problem with traction boundary conditions in either implicit solver like Ansys or explicit
solver like Abaqus or LS-Dyna. The paper would present preliminary results and findings of this approach and discuss next limitations and advantages of such an approach.
