Abstract

It is well known that the engineering properties of materials and structural components can be considerably influenced by residual stress. In this paper, a new judging method of residual stress based on improved Hilbert-Huang transform (HHT) is proposed. Two types of high strength aluminum alloy plate with or without the residual stress is analyzed by this technique. The cross correlation coefficients of each intrinsic mode function (IMF) under the two conditions are given. The results show that the changing regulations can be got and the IMF component which is great influenced by the residual stress can also be found out by this method.
