I'm looking for a chart / information that would detail the intensity limitations for a given size of media. I'm particularity interested in glass beads, but this would be good information for any type / hardness of media. Far to often I'm seeing drawings call out a size of media that is really too small to get the job done for a given intensity range. Either it's physically impossible to do what they are asking. Or by peening at extremely high velocity the glass bead explodes on first contact and or the part is not really being peened, it's being abused.
