Kiertokuorma
Kiertokuorma refers to the cumulative stress or load placed on a material or component over a period of time, particularly when subjected to repeated cycles of loading and unloading. This phenomenon is a critical consideration in engineering and materials science, as it can lead to fatigue failure, even if the applied stress remains below the material's static yield strength. The concept is often applied to structures, machines, and components that experience continuous or intermittent use.
The magnitude and frequency of the applied loads significantly influence the rate at which kiertokuorma accumulates.
Methods for assessing and managing kiertokuorma include rigorous testing, finite element analysis (FEA) to simulate stress
