Analysis of micro/mesoscale sheet stamping processes based on crystalline plasticity model

摘要

A Taylor-type crystalline plasticity model, implemented into commercial finite element analysis software, is coded as a subroutine to investigate the behavior of a stainless steel sheet with a body-centered cubic structure in this study. Thickness variations of the sheet are examined under the microgroove formation procedures. Effects of the spatial distribution of crystallographic orientations and orientation assignment approach adopted in the simulations on the thickness distribution over the sheet are demonstrated. Numerical results, based on a sheet with textured orientations, are in good agreement with the associated experimental measurements reported in the literature.View full textDownload full textKeywordscrystalline plasticity model, stamping, finite element analysisRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/02533839.2012.725821
