High-resolution 3D weld toe stress analysis and ACPD method for weld toe fatigue crack initiation [PDF]
, 2019 Weld toe fatigue crack initiation is highly dependent on the local weld toe stress-concentrating geometry including any inherent flaws. These flaws are responsible for premature fatigue crack initiation (FCI) and must be minimised to maximise the fatigue

Fatigue Crack Propagation in Polycarbonate
Journal of the Society of Materials Science, Japan, 1970 Various studies have so far been made of fatigue crack propagation about all kinds of engineering materials, but as its essential mechanism has not yet been known an experiment was performed on plane bending fatigue test using a Polycarbonate plate for specimen, and the same is reported hereunder in this paper.The relation that the differentials of the

Influence of surface recrystallization on the low cycle fatigue behaviour of a single crystal superalloy [PDF]
, 2014 This paper investigated the effect of surface recrystallization (RX) on the low cycle fatigue (LCF) behaviour of a single crystal (SX) superalloy. LCF tests on both raw and recrystallized samples showed that fatigue life was significantly reduced by ...
