What is Fatigue?
Fatigue, in the realm of engineering materials, is a phenomenon characterized by the progressive and localized damage that occurs in a material subjected to cyclic loading. Unlike static loading, where a constant force is applied, cyclic loading involves repetitive and fluctuating stress levels. This cyclic stress can result in microscopic cracks, deformations, and ultimately structural failure over time, even when the applied stress is well below the material's ultimate strength. Essentially, fatigue is the manifestation of a material's finite ability to withstand repeated loading and unloading cycles, making it a critical consideration in the design and analysis of components exposed to dynamic and variable forces.
Understanding fatigue is essential for engineers as it provides insights into the lifespan and performance of materials under real-world operating conditions. By comprehending how cyclic stresses affect different parts of a structure, engineers can predict potential failure points and design components that are not only strong but also resilient in the face of repeated mechanical stresses. This knowledge forms the foundation for fatigue analysis, a pivotal aspect of SolidWorks' capabilities, enabling engineers to create designs that not only meet static strength requirements but also exhibit durability over extended operational periods.
