|ABSTRACT: This paper presents a brief explanation of the forging process, results of experimental investigation and computational analysis on |
|the method of up seting conical test to determine the coefficient of friction for aluminum alloy AA6351. Theoretical curves were constructed |
|calibration coefficient of friction for aluminum, were also performed computer simulations of the test tube, allowing the verification of the |
|theoretical flow of material within the specimens by comparing them with results obtained in practical tests, proving the efficiency of the |
|simulation model, since the geometry of the tube facilitates the comparison between simulation and experimental tests. |
