Time-dependent springback prediction with stress relaxation effect for non-isothermal hot stam** of titanium alloy sheets
The hot stam** of titanium alloy sheets is a non-isothermal forming process due to the interfacial heat transfer while hot blank is formed and cooled in cold forming tools. Due to the condition of high tempe...

Study on the crushing and hydroforming processes of tubes in a trapezoid-sectional die
A study on the bulging processes of tubes in a trapezoid-sectional die has been carried out through finite-element (FE) analysis. A FE model of the single-step hydroforming process and several FE models of cru...
