Abstract：

The forming limit determination of 5083 aluminum alloy sheet is not only low in accuracy but also complicated in the experimental process and high in cost. Therefore, in order to obtain the forming limit of 5083 aluminum alloy material more accurately and reduce the cost of result, the forming limit of 5083 aluminum alloy was investigated by using digital image correlation method technology and Nakajima experiment, and the 5083 aluminum alloy material was made into sheets with different size to change the stress state and simulate the three stress states of unidirectional tension, plane strain and equal double tension that the material suffered practice. Then, the experimental data of 5083 aluminum alloy material were processed by the strain rate criterion to obtain the forming limit curve (FLC) of 5083 aluminum alloy under the experimental conditions. Furthermore, in order to predict the forming limit of 5083 aluminum alloy material conveniently and quickly, a mathematical model of the forming limit for 5083 aluminum alloy was established and the model prediction and experiment results have a high degree of overlap, which provides a good basis for predicting the forming limit of 5083 aluminum alloy.
