Abstract: Experiments were conducted to determine the effect of interface friction and specimen geometry on the useful ductile flow limit of 1100 aluminum and 1095 steel at room temperature. The tests ...

Abstract: The paper describes the results of hot and warm forging tests on aluminum specimens, using a modified Hopkinson pressure-bar in which impact velocities up to 100 m/s could be obtained. The ...

Abstract: A numerical method for slip-line field analysis of rigid perfectly plastic material is presented. The method formulates the analysis of metal forming operations as constrained optimization problems. ...

Abstract: This paper presents experimental results obtained for a variety of drawbeads typical of automotive applications, and compares the results with those obtained from the numerical model presented ...
