Influence of Residual Stress on the Initiation of Fatigue Cracks at Welded Piping Joints
… failure and indicated that welding residual stresses might be responsible for inducing this strain ratcheting response. It was the primary objective in this investigation to determine what happens to residual stresses at the welded piping joint under the application of low-cycle fatigue …

Mittelspannungseinfluss bei dauerfester Auslegung von Wellen und Achsen
Geometrie, Werkstoff und Belastung sind die maßgeblichen Faktoren, welche die Dauerfestigkeit beeinflussen. Allgemein bekannt ist, dass die Dauerfestigkeit bei einer Überlagerung von ruhenden und schwingenden Belastungen geringer ist als bei rein schwingenden Belastungen. Dieser Effekt wird …

DEVELOPMENT OF FATIGUE MODELS FOR COPPER TRACES ON PRINTED WIRING ASSEMBLIES UNDER QUASI-STATIC CYCLIC MECHANICAL BENDING
… tests, finite element (FE) modeling of the stresses generated during the cyclic bending tests, and response surfaces (RS) to facilitate iterative assessment of the model constants. Cyclic three-point bend tests were conducted on land grid array (LGA) components during this investigation. …
