ISO 12108:2018 Metallic materials - Fatigue testing - Fatigue crack growth method

standard by International Organization for Standardization, 07/01/2018

Full Description

This document describes tests for determining the fatigue crack growth rate from the fatigue crack growth threshold stress-intensity factor range, K_th, to the onset of rapid, unstable fracture.

This document is primarily intended for use in evaluating isotropic metallic materials under predominantly linear-elastic stress conditions and with force applied only perpendicular to the crack plane (mode I stress condition), and with a constant force ratio, R.
