Abstract
Two-stage loading tests corresponding to high-low loading and low-high loading were performed to clarify the cumulative damage properties of two kinds of aluminum alloy welded joints such as the corner joint and butt joint. As a result, the logarithmic value of cumulative damage can better be characterized by the normal distribution in accordance with the Komogorov-Smirnov goodness of fit test. The proposed linear cumulative damage model can better reflect the scatter characteristic of test data, as well as the newly developed nonlinear cumulative damage model can better characterize the effects of load sequence and load level on fatigue damage value, which was verified with the obtained test data.
