Fáradástesztelés

Fáradástesztelés, commonly known as fatigue testing, is a crucial aspect of material science and engineering that involves subjecting a material or structure to repeated cycles of stress or strain. The primary goal is to determine the material's resistance to failure under such conditions, often referred to as its fatigue life. This type of testing is vital for predicting the lifespan of components that experience cyclic loading in their operational environment, such as aircraft wings, bridges, and engine parts.

The testing process typically involves applying a controlled load or displacement to a specimen and repeating this cycle thousands or even millions of times. Various types of fatigue tests exist, including tension-compression, bending, and torsional fatigue tests, each designed to simulate different loading scenarios. The results are usually presented in the form of an S-N curve (stress-number of cycles), which illustrates the relationship between the applied stress amplitude and the number of cycles the material can withstand before failure.

Understanding fatigue behavior is essential for ensuring the safety and reliability of engineered products. By identifying potential failure points and establishing safe operating limits, fáradástesztelés helps engineers design more robust and durable structures, preventing catastrophic failures and extending the service life of critical components. It is a predictive tool that informs material selection, design optimization, and maintenance schedules, ultimately contributing to enhanced safety and economic efficiency.
