There are four classifications of cyclic stresses in fatigue
{"Image DocumentName": "There are four classifications of cyclic stresses in fatigue", "Image ImageDescription": "There are four classifications of cyclic stresses in fatigue. A cycle is each complete application of the stress. The stress ratio (R) of a cyclic stress is the minimum stress divided by the maximum stress (smin \u00f7 smax). The four classifications of cyclic stresses are low and high tensile stress (R > 0), zero stress and tensile stress (R = 0), unequal tensile stress and compression stress (R < 0), and equal tensile stress and compression stress (R = \u20131). See Figure 3-3. A cycle is one complete application of stress. With reciprocating or rotating components, the time and stress magnitude of each cycle is usually equal (uniform loading). This is not the case with other components such as automobiles, airplanes, and ships that are randomly loaded.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
