Plastic Forming of Sheet Metal with the Help of a Spherical Punch

  • A. E. Titlyanov


The stress-deformed state of a sheet metal during local forming with a spherical punch is studied in this work. The effect of the following factors on the plastic friction in a blank was studied: the friction conditions on the surface of the punch, the hardening of the material during deformation, and the dimensions of the stamp which are determined by the punch radius and the internal radius of the die.
