Metallic materials. Fatigue testing. Fatigue crack growth method1 Scope This document describes tests for determining the fatigue crack growth rate from the fatigue crack growth threshold stress intensity factor range, Kth, 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

Both detection methods are based on real-time PCR and can be used for qualitative screening purposes

for height adjustment

The tests detailed in 9

require close attention to the quality of the power produced

The coatings consist principally of zinc and can be lubricated to give controlled torque/clamping force properties when required

The proposed method of this standard is based on a numerical time integration algorithm
