Forming the Hollow Parts out of Stamped Blanks by Hydroelastic Die against Rigid Punch with Contoured Forcing Support

Stress and strain analysis of areas, that are characteristic of the stamped blank transition zone (flange, trailing edge) and have effect on the hydroelastic die pressure in the process of forming the axial symmetric part against the rigid punch with the contoured forcing support, is conducted for cases of the conic and torus-shaped hollow.
