Fatigue Test
Materials Engineering · Quality, Testing & Inspection · Last updated: July 30, 2026 · How this entry was written
Definition: A fatigue test subjects a specimen to repeated or cyclic loading to determine its endurance limit and fatigue life. It simulates long‑term service conditions where failure occurs below the static strength due to cumulative damage.
Example in context
“The fatigue test for the turbine blade was run at 600 Hz to evaluate the high‑cycle fatigue resistance of the nickel‑based superalloy.”
“Türbin kanadı için yorulma testi, nikel bazlı süperalaşımın yüksek çevrimli yorulma direncini değerlendirmek amacıyla 600 Hz'de gerçekleştirildi.”
Where engineers use it
Performed to characterize the S‑N curve of a material. Design engineers use fatigue test data to set inspection intervals, predict component life, and avoid catastrophic in‑service failures.
Synonyms: cyclic fatigue test, S‑N test
In Quality, Testing & Inspection
A test in which a specimen or component is subjected to many cycles of fluctuating load to determine how many cycles it survives before a crack initiates and grows to failure.
“The bracket survived two million cycles in the fatigue test, so the design was accepted for the vehicle's expected service life.”
Practice: can you use “Fatigue Test” at work?
You are assigned to qualify a new spring steel for automotive suspension. Design a fatigue test programme that determines the endurance limit at 10⁷ cycles.
