La fatiga is the situation in which different types of parts subjected to cyclic loading and that vary over time. This is the most common reason among most parts and components.
El ensayo de fatiga has a clear objective and that is to analyze the resistance characteristics of different materials when working under variable loads. Among these materials we can find rotating drive shafts, anchor bolts, bars, various structures, pivot shafts, shock absorbers and even asphalt or bituminous mix (to see how deterioration evolves with the passage of time and progressive degradation).
Algunos fundamental parameters to be measured by the fatigue machines in the materials are:
- Kinetics of the applied load over time.
- Type of stresses generated in the part as a result of the application of the load.
- Type of work characteristic of the machine part assembly.
- In addition, some of the most important fatigue tests are:
- Constant amplitude fatigue test: Evaluates the fatigue behavior of the part through predetermined cycles of load or deformation.
- Variable amplitude test: The purpose is to evaluate the effect of accumulated damage due to the variation of stress amplitude over time.
- Fracture test: The part is subjected to a series of deformations until it finally separates into two or more pieces.
- Prueba de altas temperaturas: este tipo de ensayo estudia el comportamiento de una pieza cuando se aplica un esfuerzo constante a una probeta sometida a una alta temperatura.
- Cold deformation: occurs when the material hardens progressively as the plastic deformation increases. Neither recrystallization nor recovery phenomena occur.
- Hot deformation: when a material is hot deformed, recovery and recrystallization occur simultaneously with the deformation.
