摘要: Tubular channel angular pressing Trapezoidal geometry Finite element method Plastic deformation (TCAP) is a recently invented severe plastic technique for producing UFG tubes. analysis using the finite (FEM) was carried out to investigate effects of trapezoidal on strain inhomogeneity index (SII), level and required load compared previously-used geometries. The results showed that SII decreases 0.003 in case while it 0.13 0.24 cases semicircular triangular types, respectively. It means excellent homogeneity achieved TCAP processing geometry. 41% lower than but almost same channel. From point view better requiring process load, an
