Abstract: The database constructed in this study enables us to input quantitative data related to crystallographic orientation to elucidate the properties of change of crystallographic orientation during bending of fine-grained materials. The obtained results are summarized as follows; (1) A crystal orientation tabulation program was produced. The crystallographic orientation distribution on the ND plane was computed quantitatively using Euler angle data acquired from SEM-EBSD analysis, so that quantitative data can be input into a database. (2) A devised algorithm was created, which can input combined data sets of the texture accumulation ratio and IPF figure of crystallographic orientation to three specific orientations of[001], [101], and [111], and the quantitative data of springback. (3) To date, 75 data of about 22.3 MB, including 37 data of purecopper, 25 data of pure aluminum, and 13 data of various steels, have been stored in the database. (4) The database proposed in this paper is useful for estimation of springback based on the stochastic analysis with Weibull distribution.
