| Research Abstract |
A forming analysis method considering size effects of deformation and friction appearing in micro/meso-scale has been developed. Molecular dynamics calculations using interatomic potentials for tool/material interfaces that were determined by first principles electronic state calculation were used to estimate the friction coefficients for each crystallographic orientation of material surface. These friction coefficients were applied to the finiteelementpolycrystal-model method considering crystal plasticity. The developed method can analyze the effect of locally and historically different friction states on deformation anisotropy. For verification of this analysis method, a measuring method for adhesion process using contact potential difference and a direct measuring method for friction force acting at tool surface were also developed.
