...Abstract Abstract A characteristic feature of bending is the inhomogeneous (nonuniform) nature of the deformation. Therefore, in a bent specimen, the strain and stress at a given point are dependent on the location of the point with respect to the neutral axis of the cross-sectional area...

... dimensions may become undersize due to the presence of residual stresses in a heat treated part. Because unequal removal of metal is difficult to avoid, excessive distortion associated with nonuniform stress relief can take place during finish machining. Excessive distortion can also result from localized...

... by the initial density of the powder. However, to describe the peculiar deformation pattern, it is necessary to account for the nonuniform stresses in the powder caused at the initial stages of HIP by the capsule and temperature field and to account for the resulting nonuniform densification. The deviatoric...

... can tolerate preheating without excessive oxidation. Once the first pass has been accomplished, the reduction per pass can be decreased, as is often desirable because roll-separating forces increase as the parts to be rolled become thinner. However, the nonuniform stress distribution that builds up...

... of the cylindrical surface. Under these circumstances, for L / D ratios on the order of 2.0, a double barrel forms, as shown in Fig. 1(c) , smaller L / D ratios lead to a single barrel, as in Fig. 1(d) . Barreling indicates that the deformation is nonuniform (i.e., the stress and strain vary throughout...
