Fatigue Testing

Metallic material fatigue testing standards are published by ISO. The ISO 12110 series covers general test method principles and data reduction methods and is a good starting point for those who want standardized fatigue testing. A variety of methods are covered, including the crack growth method, thermomechanical method, axial and uniaxial methods, bar bending testing, and torque-controlled methods. Many documents also outline statistical analysis and maintenance of fatigue testing machines. These standards are invaluable to those who design large load-bearing structures, such as infrastructure like bridges or even those who work in the aerospace industry where many trust their safety to the designers’ creations.

Metallic materials - Fatigue testing - Fatigue crack growth method

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 .

Metallic materials - Fatigue testing - Statistical planning and analysis of data

ISO 12107:2012 presents methods for the experimental planning of fatigue testing and the statistical analysis of the resulting data. The purpose is to determine the fatigue properties of metallic materials with both a high degree of confidence and a practical number of specimens.

ISO 12111:2011

Metallic materials - Fatigue testing - Strain-controlled thermomechanical fatigue testing method

ISO 12111:2011 is applicable to the TMF (thermomechanical fatigue) testing of uniaxially loaded metallic specimens under strain control. Specifications allow for any constant cyclic amplitude of mechanical strain and temperature with any constant cyclic mechanical strain ratio and any constant cyclic temperature-mechanical strain phasing.

ISO 12106:2017

Metallic materials - Fatigue testing - Axial-strain-controlled method

ISO 12106:2017 specifies a method of testing uniaxially deformed specimens under strain control at constant amplitude, uniform temperature and fixed strain ratios including at R e = 1 for the determination of fatigue properties. It can also be used as a guide for testing under other R -ratios, as well as elevated temperatures where creep deformation effects may be active.

ISO 1099:2017

Metallic materials - Fatigue testing - Axial force-controlled method

ISO 1099:2017 specifies the conditions for conducting axial, constant-amplitude, force-controlled, fatigue tests at ambient temperature on metallic specimens, without deliberately introduced stress concentrations. The object of testing while employing this document is to provide fatigue information, such as the relation between applied stress and number of cycles to failure for a given material condition, such as hardness and microstructure, at various stress ratios. While the form, preparation and testing of specimens of circular and rectangular cross-section are described, component testing and other specialized forms of testing are not included in this document.

Metallic materials - Rotating bar bending fatigue testing

This document specifies the method for rotating bar bending fatigue testing of metallic materials. The tests are conducted at room temperature or elevated temperature in air, the specimen being rotated. Fatigue tests on notched specimens are not covered by this document, since the shape and size of notched specimens have not been standardized. However, fatigue test procedures described in this document can be applied to fatigue tests of notched specimens.

Metallic materials - Torque-controlled fatigue testing

This document specifies the conditions for performing torsional, constant-amplitude, nominally elastic stress fatigue tests on metallic specimens without deliberately introducing stress concentrations. The tests are typically carried out at ambient temperature or an elevated temperature in air by applying a pure couple to the specimen about its longitudinal axis. While the form, preparation and testing of specimens of circular cross-section and tubular cross-section are described in this document, component and other specialized types of testing are not included. Similarly, low-cycle torsional fatigue tests carried out under constant-amplitude angular displacement control, which lead to failure in a few thousand cycles, are also excluded.
