| Popis: | Rolling edge crack of 5052 aluminum alloy under one-pass (reductions of 35%, 40%, 50%, 60%, respectively) and multi-pass rolling at total reductions of 60% (two-pass, three-pass, four-pass and five-pass, respectively) at room temperature was analyzed by numerical simulation combined with experiments. Through the simulation of rolling process, damage was obtained. The maximum damage concentrated in the edge position and grew gradually with the increase of reduction (one-pass). As changing the rolling passes, damage with three-pass rolling is the least. Experimental results and simulation results were in good agreement. The optimum rolling scheme under 60% reductions was 3-time rolling with the least crack length (test: 1.3 mm, simulation: 1.4 mm, error of 7%). |
