Initial/residual stress due to shot peening process
Initial/residual stress due to shot peening process
(OP)
I am trying to apply some initial compressive stress to the surface of a casting due to the shot peening process. I was wondering if anyone has any experience with this? I am looking to apply this initial stress as a function of depth into the surface. Does anyone know if this is possible using the INISTATE command?

A layer-, element- or integration-point-wise varying INISTRESS seems more like it (again see gurmeet2003), but a varying Modulus may appeal - if you think of calibrating against failure based on admissible strains. I.e. if instead of looking at admissible stresses you use strains as the design criteria.
