In order to measure the flow curves of steel sheets at high temperatures, which are dependent on strain and strain rate as well as temperature and temperature history, a tensile test machine and specimens were newly developed in this work. Besides, a

The frictionless dome test can be used to evaluate formability and determine the flow stress curve of sheet materials under biaxial forming conditions. The flow stress curve, obtained from the frictionless dome test can be determined up to larger str

Most failures of ductile materials in metal forming processes occurred due to material damage evolution- void nucleation, growth and coalescence of neighboring voids. Recently, Gologanu-Leblond-Devaux (J. Mech. Phys. Solids, Vol.41 (1993), pp.1723-17

A torque converter impeller hub is usually made through sequential cold forming processes: forward extrusion, upsetting, piercing and finishing. The finishing process is a closed-die forging where the load increases abruptly due to flash formation an

In sheet metal forming operations, the formability of sheet metals is limited by the occurrence of internal damage evolution that eventually yields a localized neck. Thus, designing and optimizing a sheet metal forming process, requires the precise p
