Fatigue Fatigue is the lowering of strength or failure of a material due to repetitive stress, which may be above or below the yield strength.
{"Image DocumentName": "FatigueFatigue is the lowering of strength or failure of a material due to repetitive stress, which may be above or below the yield strength.", "Image ImageDescription": "Many engineering materials such as those used in cars, planes, turbine engines, machinery, shoes, etc are subjected constantly to repetitive stresses in the form of tension, compression, bending, vibration, thermal expansion and contraction or other stresses. At a local size scale, the stress intensity exceeds the yield strength. For fatigue to occur at least part of the stress in the material has to be tensile. Fatigue is most common in metals and plastics, whereas ceramics fail catastrophically without fatigue because of their low fracture toughness.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
