Stress-corrosion cracking. ... If either factor is eliminated, stress-corrosion cracking cannot occur.

Striations or beachmarks?
https://www.tec-eurolab.com/eu-en/striations-or-beachmarks.aspx

The other difference between striations and beachmarks, as previously mentioned, is the factors that cause them. ... Consequently, the fatigue action causes the necessary tensile stress at this location when the load is released, not when it is applied.

Stages of fatigue failure
https://www.tec-eurolab.com/eu-en/stages-of-fatigue-failure.aspx

The propagation stage of fatigue causes the microcrack to change direction and grow perpendicular to the tensile stress.... As the propagation of the fatigue crack continues, gradually reducing the cross-sectional area of the part or test specimen, it eventually weakens the part so greatly that final, complete fracture can occur with only one more load [...]

Fatigue crack growth rate, da/dN
https://www.tec-eurolab.com/eu-en/fatigue-crack-growth-rate-dadn.aspx

Glossary of terms > Fatigue crack growth rate, da/dN Fatigue crack growth rate, da/dN The rate of crack extension caused by constant-amplitude fatigue loading, expressed in terms of crack extension per cycle of load application.

Penetrability

Insights > Stress Corrosion Cracking (SCC) type corrosion of flexible inox pipe Stress Corrosion Cracking (SCC) type corrosion of flexible inox pipe The objective was to define the corrosion causes Starting from visual analysis and classification it proceded by classifying the phenomenon in terms of chemistry and metallurgy of the metal [...]

Corrosion

Erosion is a strictly mechanical form of corrosion that is caused by friction. There is another type of erosion, which is caused by high speed water flow.

Microscopic characteristics of fatigue failure
https://www.tec-eurolab.com/eu-en/microscopic-characteristics-of-fatigue-failure.aspx

However, as the crack gradually propagates, the spacing between striations increases and the crack grows at an increasingly rapid rate because the crack greatly weakens the section. ... Artifacts caused by rubbing or other postfracture damage may produce parallel ridges that resemble striations.

Causes of brittle fracture
https://www.tec-eurolab.com/eu-en/causes-of-brittle-fracture.aspx

Glossary of terms > Causes of brittle fracture Causes of brittle fracture Brittle fractures that occur in service are invariably initiated by defects that are initially present in the manufactured product or fabricated structure or by defects that develop during service. ... Notches, which are discontinuities caused by abrupt changes in the [...]

Compression fatigue

Consequently, the fatigue action causes the necessary tensile stress at this location when the load is released, not when it is applied. With continued operation, radial fatigue cracks will form at the upper corner.
