Abstract


  • ,is paper presents a constitutive modelling of the polycrystalline thin metal strip under a state of combined loading in

    microflexible rolling. ,e concept of grained inhomogeneity is incorporated into the classic Chaboche hardening model that

    accounts for the Bauschinger effect, in order to provide more precise description and analysis of the springback mechanism in the

    particular forming operation. ,e model is first implemented in the finite element program ABAQUS to numerically predict the

    stress-strain relationship of 304 stainless steel specimens over a range of average grain sizes. After validation of the developed

    model by comparison of predicted curves and actual stress-strain data points, it is further applied to predict the thickness

    directional springback in microflexible rolling of 304 stainless steel strips with initial thickness of 250 μm and reduction changing

    from 5 to 10%. ,e model predictions show a reasonable agreement with the experimental measurements and have proven to be

    more accurate than those obtained from the conventional multilinear isotropic hardening model in combination with the Voronoi

    tessellation technique. In addition, the variation of thickness directional springback along with the scatter effect is compared and

    analysed in regard to the average grain size utilising both qualitative and quantitative approaches in respect of distinct types of data

    at different reductions.
