cyclical loading

Cyclical loading refers to the repeated application and removal of forces or pressures on a material or structure over time. This can happen, for example, with bridges experiencing regular traffic or machinery subjected to ongoing vibrations. Each cycle of load and unload can cause gradual changes in the material’s properties, such as wear or fatigue, potentially leading to cracks or failure if the cycles are frequent or intense enough. Understanding cyclical loading is important for predicting how structures will behave and ensuring their safety and durability over time.
