FD&E Total Life T-Sample Residual Stress Analytical Predictions and Measured Results

The SAE Fatigue Design & Evaluation Committee is actively working on a total life project for weldments, in which the welding residual stress is a key contributor to an accurate assessment of fatigue life. Physics-based welding process simulation and various types of residual stress measurement were pursued to provide a sufficiently accurate representation of the residual stress field at the failure location in the fatigue samples. A well-controlled and documented robotic welding process was used for all sample fabrication to provide accurate inputs for the welding simulations. Both destructive (contour method, x-ray diffraction (XRD) with etching) and non-destructive (surface XRD, energy dispersive diffraction (EDD), neutron diffraction(ND)) residual stress measurements were performed on the same or similarly welded samples. The sample is constructed with multiple-pass fillet welds, which induce large gradients in residual stress through the one-inch thickness.

Standardization of Graphics for Service Information and Translation Expense Reduction

The cost of human natural language translation of Service Information, Assembly Instructions, Training Materials, Operator Manuals and other similar documents is a major expense for manufacturers. One translation avoidance method involves replacing most of a document’s text with still and/or animated graphics. While the graphics with minimum text concept has savings potential, clarity of communication must be maintained for widespread application of this technique. The necessary clarity should be achieved if standards are established for the symbols and graphical conventions used. This paper provides an example of a repair procedure documented using the graphics with minimum text paradigm, describes many of the anticipated standards and provides an update on the progress towards achieving a standard development project.
