Description
  • Contribution concerns formability evaluation of low-carbon steel strip St 4, which is used for production of intricate deep stampings. The properties of sheet-metal which have the principal influence upon the success of deep drawing or strech-forming are described, i. e. directional and mean values of mechanical properties, the values of coefficients of planar anisotropy of mechanical properties, directional and mean values of coefficients of normal plastic anisotropy ratio, directional and mean values of strain-hardening exponents. From values, evaluated by tensile tests, the forming limit diagram, which comes out from criterion of plastic deformation stability loss at the tensile strength, can be constructed. These diagrams are advantageous for comparison of sheet-metal plastic properties at various stress states or in range of stresses according to the working up technology.
