... (plastic deformation) on the properties of the workpiece. The most often analyzed effect of forming is the Bauschinger effect. It is a phenomenon in which plastic deformation of polycrystalline metal, caused by stress applied in one direction, reduces the yield strength when the stress is applied in the...

... stresses are mostly detrimental, in some cases, intentionally induced residual stresses may be a part of the process to counter service-imposed stresses. Excess residual stresses also can result in the loss of yield strength due to the Bauschinger effect ( Ref 30 ). This is a phenomenon wherein the...

... unanticipated properties have been attributed to the Bauschinger Effect (that is, a reduction of the yield stress following a stress reversal) and to residual stress. Decreasing yield stress with continued reduction, to a minimum at 20 to 30% area reduction, has been observed during the swaging of rifle...

.... These include nonuniform hot forging or deformation, cold forming and straightening, asymmetric machining of plates and forgings, and welding/cooling operations. Stress-removal prevents distortion by maintaining shape stability. It eliminates the Bauschinger effect: lower compressive or tensile yield...

... puts the surface under compression. This change from tensile to compressive load (or vice versa) may influence the flow curve and is known as the Bauschinger effect. In simulation, this is usually modeled by isotropic or kinematic strengthening. The Bauschinger effect of undercooled aluminum alloys has...
