| Description
| - The paer contains results of an experimental investigation of surface and near sub-surface resiadual stresses induced by shot peening with two groups of parameters of both sidesear edges of fairly thin plated sheets of a V-95 aircraft Al-alloy. Residual stresses were evaluated using two very different methods: (i) by strain gauge measurement of gradual surface stress relaxation during grinding the opposite surface off and (ii) by X-ray diffraction method performed directly on the specimen surface and in the near sub-surface area after etching the surface layer off. Though the methods were very different, they both confirmed that longitudinal residual stresses in the subsurface location were as expected of the compressive type, but surprisingly low, no more than several tens of MPa. This result was rather unexpected because particularly one group of the peening parameters was quite severe. Nevertheless the shot peening effect on initiation and growth of physically short fatigue crack was significant. Before the shot peening, physically short fatigue cracks of the length from 0.2 mm to more than 3 mm, most of them between 0.8-1.5 mm, were prepared under high cycle fatigue loading of a constant nominal stress amplitude +/- 160 MPa.
