Bending Strength of Spur Gear Teeth : 1st Report, Cumulative Fatigue Damage of Normalized 0.45% Carbon Steel

Damage Detection of Carbon Fiber-reinforced Concrete Under Bending Test

Bending Fatigue Failures in Valve Steel

In the present paper the effect of defects (viz. pits, gouges and oxide inclusions) will be reported. Although certain defects were uniformly distributed over the specimen surface, the majority of all fractures started in the edge region. An explanation to this behaviour is presented in terms of stress enhancement in the edge regions due to edge deflections.

Cumulative Fatigue Damage Under stepwise Tension-Compression Loading

Rock structures are subjected to cyclic tension-compression loading due to a blasting, earthquake, traffic and injection-production in underground storage case. Therefore study the fatigue behavior of rock samples under this type of loading is required. In this study, the accumulated fatigue damage for a Green Onyx rock sample which consisted of only one mineral composition with two-step high-l...

Failure Investigation of Hydrogen Blistering on Low-strength Carbon Steel

The current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. For this purpose, some experiments including hardness test, non-destructive test (NDT), metallography, and fractograpghy are conducted. The microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (SEM). The microstructural studies show that t...
