Verification and Analysis of Stress-Strain Curve of Sheet Metal by using Three Roller Bending Machine

  C. S. Jadhav,  Prof. P.S.Talmale

Roller bending process is used to transform a sheet or plate into hollow cylindrical shapes implementing plastic deformation techniques. Cylindrical and conical shells are basic component of vessels and structures used for various engineering applications. In these cases, it is important to bend the sheet safely and working for longer life. In bending operation a metal sheet is subjected to sequential bending stresses for different position of top roller. Advanced techniques are used for verification of stress values up to ultimate tensile strength of material. In this paper work has been carried on analytical, FEA analysis. Stresses produces in sheet metal are comparing with analytical and FEA. Also stress-strain curves obtained in analytical and FEA analysis are nearer to each other.
