ASTM E466 – Force-controlled constant amplitude axial fatigue testing of metallic materials
ASTM E466 is the ASTM practice for conducting force-controlled constant amplitude axial fatigue tests of metallic materials in the high-cycle regime. To match this to your program, talk with our team.
What ASTM E466 Covers
It defines how to run axial fatigue tests on unnotched and notched metallic specimens under a constant amplitude, periodic force, where strains stay predominantly elastic. It applies to specimens rather than finished components.
How the Test Is Run
A polished axial specimen is cycled between fixed force limits at a chosen stress ratio and frequency until failure or run-out, and the results build the stress-life (S-N) curve for the material.
Why It Matters
High-cycle fatigue strength drives the safe life of many metal parts; consistent specimen preparation, surface finish, and alignment are essential to avoid premature or scattered failures.
