WebThese conditions are called fully-reversed cycle fatigue and repeated stress cycle fatigue. Fully-reversed fatigue loading involves the material being loaded in tension (which is considered positive stress) and compression (negative stress) within a single cycle. The magnitude of the alternating stress σ a is the same in tension and compression.

WebFor idler or epicyclic planet gears, stresses are fully reversed and the extreme case of an R ratio of-1.0 occurs. The Single Tooth Reversible Bending Fatigue (STRBF) test outlined herein overcomes previous limitations by allowing compressive stresses to be applied to the test tooth root in any magnitude in conjunction with the typical tensile ... WebReversed loading:-. It is a loading condition where an object is subjected to alternating tensile and compressive stresses. Here the mean stress is 0. A reversed cyclic loading means when the stress alternates between equal positive and negative peak stresses during cycle of operation.
