Cyclic loading refers to the repeated, fluctuating application of mechanical or thermal stresses to a component over time. It is a critical parameter in structural engineering as it leads to material fatigue and eventual microstructural failure, even at stress levels well below the material's yield strength.
Repeatedly applied mechanical forces or stress cycles that can cause fatigue wear, structural degradation, and eventual mechanical failure in industrial components over time.
The repeating mechanical stress induced in a material due to rapid or recurring changes in temperature. Engineers must calculate and minimize this stress to prevent thermal fatigue cracking and ensure a long service life for equipment subjected to batch operations or rapid thermal cycles.
