API-571 Exam - Question 26


The amplitude and frequency of vibration as well as the _________ of the components are critical factors in vibration-induced fatigue.

Show Answer
Correct Answer: CD

The amplitude and frequency of vibration, as well as the material properties of the components, are critical factors in vibration-induced fatigue. Material properties, such as strength, hardness, and microstructure, directly influence how a material responds to cyclic stresses and strains, making it a key factor in determining the fatigue life of a component.

The amplitude and frequency of vibrations (related to stress level and number of cycles) in vibrating equipment such as piping are also critical factors.

Geometry, stress level, number of cycles, and material properties (strength, hardness, microstructure) are predominant factors in determining the fatigue resistance of a component. The amplitude and frequency of vibrations (related to stress level and number of cycles) in vibrating equipment such as piping are also critical factors.
