摘要: ABSTRACTResidual stresses are frequently evaluated using two types of tests: destructive and non-destructive. The most common type non-destructive test examines the relationship between physical parameters measured by X-ray diffraction. This technique requires a small sample size planar surface. In metal forming, geometry different pieces is complex, surfaces curved. work utilizes an indirect method to evaluate residual present in cold forming non-flat corrosion deformation region. Samples from AISI 1045 steel were bent angles 150°, 120°, 90°, 45°. samples then subjected potential difference (PD) results compared those unbent sample. bending process was simulated finite element that revealed intensity nature samples. statistically treated demonstrate P...
