Periodic loading of components eventually leads to breaking. In order to ensure maximum reliability, having in-depth knowledge about the durability is essential. Electromagnetic high frequency pulsators (Vibrophores) offer an extremely efficient solution for determining the mechanical properties of materials at high frequencies and forces. Chongqing University in central China will be using a Vibrophore with 1,000 kN in the future. The durability of components provides information about how many load cycles are permitted before leading to failure or break. It is therefore used as a key factor for designing crankshafts, connecting rods, and timing chains in motor-vehicle engines, connection elements in airplanes or concrete-reinforcing steel in power plants. Durability is typically determined through the application of periodic loads in fatigue tests. The resulting limit curve is known as the Wöhler (S-N) curve. It shows the correlation between the number of cycles to failure and the cyclic stress amplitude. The curve diagram is named after August Wöhler who developed the test after a railroad accident in 1875 that was caused by a tire failure. He recognized that periodically loaded components have shorter life spans than those where only static forces are applied. The cause of the wheel failure was not a material defect but rather material fatigue, which was a fundamental realization for future developments in quality assurance.
