Abstract

In the present study, it was attempted to perform the RESIDUAL STRESS analysis in the aluminum sheets A.A5083 via experimental results of hot metal FORMING process by gas. Then the accuracy of simulations was evaluated by the FINITE ELEMENT Method and its comparison with experimental tests. The aim of the present study was to apply an efficient approach to determine the stresses caused during the FORMING process. Thus, the inductive stress in the imperfect conical sheets produced by gas blow process was measured method via hole DRILLING. In the experimental test, the stress equal to 44.5 Mpa was obtained. Then, The temperature dependant RESIDUAL STRESSes of hot metal FORMING process were evaluated by the FINITE ELEMENT Analysis Method. To simulate the FORMING process, ABAQUS/Explicit FINITE ELEMENT software was used. The maximum of deviation in the results of FINITE ELEMENT calculations and experimental tests for the maximum stress in the piece was 7%. Thus, it was concluded that via FINITE ELEMENT calculations more accurate study on hot metal FORMING method by gas can be done.
