Relation between the total fatigue life and the fatigue crack initation life of a spot weld.
TLDR
The relation between the total fatigue life and the fatigue crack initiation life of a single spot weld tensile shear specimen was determined in this paper, and the reason why the initial stress intensity factor could control the toota fatigue life was discussed.Abstract:
The relation between the total fatigue life and the fatigue crack initiation life of a single spot weld tensile shear specimen was determined. Based on the results, the reason why the initial stress intensity factor could control the toota fatigue life was discussed. During the investigation, the methods of determination of fatigue crack initiation at the spot weld were developed, and related phenomena were elocidated.read more

3-Dimensional Observation of Fatigue Crack Propagation on Spot Welded Joints using High Strength Steel
TL;DR: In this article, the fatigue characteristics of the spot welded joints using the high strength steel were investigated and internal fatigue crack behavior around the spot area was observed in detail, and it was clarified that the spot-welded joints used in this study require many cyclic loading to initiate the fatigue crack.
