FluidForming – Hydroforming reinvented [PDF]
MATEC Web of Conferences, 2015 The FluidForming technology represents an alternative sheet metal forming approach as compared to the traditional, bladder based hydroforming, metal spinning, and sheet metal stamping processes. The machine construction allows for much higher forming pressures of up to 400 MPa/60,000 psi.

Fatigue &Fracture of Engineering Materials &Structures, Volume 43, Issue 1, Page 3-19, January 2020., 2020 Abstract For metallic materials, standard uniaxial tensile tests with round bar specimens or flat specimens only provide accurate equivalent stress–strain curve before diffuse necking. However, for numerical modelling of problems where very large strains occur, such as plastic forming and ductile damage and fracture, understanding the post‐necking ...
