摘要

The planar defects area estimation method, and the surface shape defects occur area estimation method for estimating the occurrence region of the shape defects surface of the plastic workpiece is obtained by plastic working of the material to be processed, the of acquiring a first stress distribution σ _(T1) A second stress distribution acquisition step of acquiring a second stress distribution σ _(T2) , a comparative stress distribution acquisition step of acquiring a comparative stress distribution σ _{(T1, T2)} , a comparison stress distribution σ _DIV comprises a planar defects region estimation process of estimating whether or not the divided comparison stress distribution acquiring step, a partition D _k, respectively generating region of the surface shape defects of acquiring _{(T1, T2).}
