2. Fatigue (material) - Wikipedia

   en.wikipedia.org/wiki/Fatigue_(material)

   Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved.

3. Corrosion fatigue - Wikipedia

   en.wikipedia.org/wiki/Corrosion_fatigue

   In true corrosion fatigue, the fatigue-crack-growth rate is enhanced by corrosion; this effect is seen in all three regions of the fatigue-crack growth-rate diagram. The diagram on the left is a schematic of crack-growth rate under true corrosion fatigue; the curve shifts to a lower stress-intensity-factor range in the corrosive environment.

   Average Cost: $7-$16 per square foot installed. Average Lifespan: 40-70+ years. Metal roofs are built to withstand hurricane-force winds, resist sun damage, hold up well in rain, and reflect ...

5. Striation (fatigue) - Wikipedia

   en.wikipedia.org/wiki/Striation_(fatigue)

   Scanning electron microscope image of fatigue striations produced from constant amplitude loading. The crack is growing from left to right. Striations are marks produced on the fracture surface that show the incremental growth of a fatigue crack. A striation marks the position of the crack tip at the time it was made.

6. Stress corrosion cracking - Wikipedia

   en.wikipedia.org/wiki/Stress_corrosion_cracking

   mild steel cracks in the presence of alkali (e.g. boiler cracking and caustic stress corrosion cracking) and nitrates; copper alloys crack in ammoniacal solutions (season cracking); high-tensile steels have been known to crack in an unexpectedly brittle manner in a whole variety of aqueous environments, especially when chlorides are present.

7. Notch (engineering) - Wikipedia

   en.wikipedia.org/wiki/Notch_(engineering)

   In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks. Notches are used in materials characterization to determine fracture mechanics related properties such as fracture toughness and rates of fatigue crack growth.

8. Crack closure - Wikipedia

   en.wikipedia.org/wiki/Crack_closure

   Crack closure is a phenomenon in fatigue loading, where the opposing faces of a crack remain in contact even with an external load acting on the material. As the load is increased, a critical value will be reached at which time the crack becomes open .
