The 2009 Sayano–Shushenskaya power station accident due to metal fatigue of turbine mountings. The 2017 Air France Flight 66 had in-flight engine failure due to cold dwell fatigue fracture in the fan hub. The 2023 Titan submersible implosion is thought to have occurred due to fatigue delamination of the carbon-fiber material used for the hull.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
The increased earthquakes were said to be most likely caused by increased injection of gas-well wastewater into disposal wells. [14] The injection of waste water from oil and gas operations, including from hydraulic fracturing, into saltwater disposal wells may cause bigger low-magnitude tremors, being registered up to 3.3 (M w).

Plowing occurs when material is displaced to the side, away from the wear particles, resulting in the formation of grooves that do not involve direct material removal. The displaced material forms ridges adjacent to grooves, which may be removed by subsequent passage of abrasive particles. Cutting occurs when material is separated from the ...
Solid Waste Tree, Based on Resource Conservation and Recovery Act, United States Environmental Protection Agency. Solid waste means any garbage or refuse, sludge from a wastewater treatment plant, water supply treatment plant, or an air pollution control facility and other discarded material, including solid, liquid, semi-solid, or contained gaseous material resulting from industrial ...
Fouling is the accumulation of unwanted material on solid surfaces. The fouling materials can consist of either living organisms (biofouling, organic) or a non-living substance (inorganic). Fouling is usually distinguished from other surface-growth phenomena in that it occurs on a surface of a component, system, or plant performing a defined ...

With static fatigue materials experience damage or failure under stress levels that are lower than their normal ultimate tensile strengths. [2] The exact details vary with the material type and environmental factors, such as moisture presence [3] and temperature. [4] [5] This phenomenon is closely related to stress corrosion cracking. [1]
