摘要：

It is one of the difficult problems in the manufacture of the integrated aircraft part of Machining distortion caused by residual stress. According to the characteristics of aluminum alloy pre stretched thick plate, the modified removal method for measuring residual stress in thick pre-stretched aluminum plates is proposed and the stress-strain relation matrix is deduced by elasticity theory. Moreover, the residual stresses in the specimen of 7075T7351 plate is measured by the proposed method, and the results are finally analyzed and compared with the data obtained by other methods. The results indicate that the proposed method is effective in measuring the residual stress in thick pre-stretched aluminum alloy plates. The measurement results can be used for the quantitative analysis of aerospace parts machining distortion caused by residual stress, and it has higher value in engineering application. © 2018 Trans Tech Publications, Switzerland.
