Residual Stresses and Fatigue Behavior of Welded Structural Members

The objective of the project was to study experimentally the fatigue behavior of flange plates in welded beam sections as influenced by different residual stress distributions which are caused by different sizes of welds. In connection with the project, a survey of literature on the fatigue of welded structural members was conducted. The result of this survey including a set of conclusions is presented in Part I of this report. Plate type specimens with longitudinal weld beads running along the center lines of the specimens were subjected to axial repetitive loading to simulate the behavior of the flange plates, Residual stresses were measured on a number of specimens with different plate widths and weld areas. The program is divided into the following sections: (1) pilot test series, consisting of 13 specimens; (2) a study of the effect of weld removal on residual stress distribution, and (3) main test series, consisting of 9 specimens. Although the details and the results of items (1) and (2) have been presented in a previous report, most of the information is included in this report for completeness and convenience in discussion. The program and the test results for the main test series are presented in detail in this report. The complete experimental investigation is presented in Part II of this report.
