What is the fatigue test?

Fatigue test is a type of material test in which the aim is to determine the point in which the material fails. Fatigue is a problem for all materials caused by wear and tear as they are used. During the fatigue test, the fatigue is intentionally induced to find the stress of the material. Materials for certain applications may need to meet specific requirements in terms of fatigue. For example, metals used in the bridge must be able to withstand very high voltage.

Fatigue is caused by things such as movement, oscillation, vibration, pressure, wear. In order to lend an example of the bridge, bridges are subjected to stress when they move in the wind, stress during seismic events and daily vibrations and loads of thousands of cars. Over time, fatigue leads to cracking in the material and eventually causes failure; Either the material is cut or cracks causes a fracture of structural components, which will lead to collapse.

Whether it is a frame or a bridge, fatigue is a problem. During the fatigue test, the materials used are subjected to vibrationsAnd other types of stress and carefully monitored. Once signs of fatigue begin to appear, they are recorded and monitored and map how long it takes to fatigue and possible failure. The point at which fatigue begins to occur is the lower voltage limit. Fatigue testing is sometimes referred to as dynamic testing because it includes a number of pummel techniques and basically material attack to find its stress limits.

With something like a piece of furniture, the furniture can be carried out by a fatigue test. For example, a chair can simulate someone who sinks again and again into a chair, or could create a twisting of the tension that occurs when the chair is pulled over the floor, with or without the inhabitant. In the case of large equipment, individuals AL Machine individuals are served by testing fatigue, as the whole equipment may not fit into the test area.

Fatigue testing results are stored in folders and in some cases it is necessary to be filed with a government agency. For example, people working on a height buildingIt must prove that fatigue test was carried out on components and that the components had passed. This information may be useful if the failure is failing, creating a paper trail that can be used to find out when things began to go wrong.
