Fatigue testing is a crucial method for assessing the endurance and reliability of materials subjected to repeated loading and unloading cycles. It can be performed at varying loads, speeds, and temperatures to simulate real-world conditions. The results of these tests are used to predict the lifespan of materials and parts that may be exposed to such conditions. Fatigue testing is commonly employed to assess material properties during the selection or verification process.

Both high-cycle and low-cycle fatigue testing use cyclic loading to evaluate the ability of materials to withstand fluctuating strains and stresses that may lead to cracking or fracture. These tests are essential to ensuring the safety and reliability of products, especially in industries where failure could result in severe injury or damage.

High Cycle Fatigue Test
The high-cycle fatigue test is used to evaluate the fatigue strength of materials under cyclic loading in the elastic regime. It involves applying a large number of constant amplitude direct stress cycles to the test specimen until either the specimen fails or a predetermined number of load cycles is reached without failure. Three common types of high-cycle fatigue tests are Axial Fatigue, Rotating Beam Fatigue, and Fastener Fatigue, each designed to test different types of materials and components.

Low Cycle Fatigue Test

The low-cycle fatigue test is typically performed at a slower pace and with a relatively low number of cycles to failure, typically in the range of a few hundred to a few thousand cycles. This test is characterized by high amplitude, high-frequency plastic strains, and is often conducted at elevated temperatures to simulate real-world conditions. The test involves cyclic loading that results in the development of plastic deformation in the material and can lead to the growth of microstructural defects, such as cracks and voids, which can ultimately lead to failure.
