摘要
PROBLEM TO BE SOLVED: To provide a method for accurately estimating residual stress distribution after straightening even when the shape of not only a material having almost the same yield stress at tensile deformation and compressive deformation like an annealed material and without anisotropy, but a material having large difference in the yield stress at the tensile deformation and the compressive deformation and a material having anisotropy are straightened with rolls with a straightening device such as a tension leveler and a roller leveler.;SOLUTION: When determining the residual stress of a sheet which is worked by bending or bending-back deformation when the sheet is passed through the roll straightening machine, by an analysis model combining the relational expression of the stress - strain (increment) of a material and a yield condition formula, the residual stress is estimated by taking Baushinger effect, anisotropy or the Baushinger effect and the anisotropy of the material into consideration as the yield condition.;COPYRIGHT: (C)2006,JPO&NCIPI
