Abstract: According to the characteristics of the thick pre-stretched aluminum alloy plate, a new method of measuring the residual stresses in thick plate is deduced by the elastic mechanical theory.The residual stresses distribution along the thick direction of plate 7050T7451 is measured by the new method, and the results of measurement are analyzed.It is shown that the new method deduced in this paper is simple and accurate, and is very useful in engineering.

Key words: pre-stretched aluminum plate, residual stress, layer-removed method, measurement
