"Tooling for working structure to increase the fatigue strength at a location selected in the mentioned structure.Method for working a portion limu00ectrofe material in a structure, joint, method for manufacturing a joint device for the cold working of a work piece.Method for manufacturing a workpiece to have a structure with greater life without fatigue, metal plate, method for making a metal part of a thick article of manufacture, and finished part.A high performance compound (16) for cold working of metal, and a method of employing such tooling.The tool of the compound (18) is used to produce deformation in a structure of a work piece (30) to provide a beneficial residual stress profile in the workpiece (selected.30), so as to provide structures with long life without fatigue in a minimum number of manufacturing steps.Preferably, the action of the compound (18) causes deformation of the workpiece, causing small holes in the work piece.An improved profile of the composite tool is described, having a first elongated Carver (20) with a portion of supefu00edcie of the modelled.And according to the modeled (22) surrounding the first Carver and forming an annular shoulder (44) in the recess of the portion of the surface of the first carver.In addition, a base (60) having a bottom portion (80) can be used to surround so confined, the second Carver for application of force to the surface of a work piece.To prevent deformation of the surface.
