Multiaxial Fatigue Under Variable Amplitude Loads

Journal of Engineering Materials and Technology, 1999
Multiaxial fatigue under variable amplitude loading is investigated using Kandil et al.’s parameter, rainflow cycle counting on the shear strain history, and the Miner-Palmgren damage rule. Fatigue data are obtained on tubular specimens of S45C steel under proportional and nonproportional tension-torsion loading.

Fatigue Damage under Variable Amplitude Loads

Journal of Structural Engineering, 1988
A truck passing over a bridge induces loads which vary with time. To test the ability of available analytical techniques to estimate fatigue life under such loading, crack growth rate tests are conducted with eleven compact‐type specimens using constant and variable amplitude load‐time histories.

Estimation of the opening load under variable amplitude loading

Fatigue & Fracture of Engineering Materials & Structures, 2019
AbstractThe crack opening/closure load concept is widely used to justify the fatigue crack growth behaviour with different load ratios and the load interaction effects. Many experimental techniques have been proposed to measure crack opening/closure load, and amongst them, compliance offset methods are widely used for their simplicity and consistency ...

Fatigue Reliability: Variable Amplitude Loading

Journal of the Structural Division, 1982
Models which designers use to predict fatigue under variable amplitude and random loading are summarized. Basic terminology associated with random process theory is presented. Models for computing fatigue damage associated with various statistical distributrions of stress ranges are reviewed.

Fatigue testing under variable amplitude loading

International Journal of Fatigue, 2007
Abstract There are many publications about variable amplitude test results. However, very often information on load–time histories, spectra and testing details are missing. This fact does not allow the interpretation of test results with regard to fatigue lifing and structural durability design.

Permanent Strains from Cyclic Variable‐Amplitude Loadings

Journal of Geotechnical Engineering, 1986
Cyclic triaxial tests were performed on a well‐graded railroad ballast with a maximum particle size of 38 mm (1.5 in.). Samples were compacted in a split mold to reproduceable density states and subjected to repeated applications of compressive axial stresses.

Crack Opening Under Variable Amplitude Loads

1989
Crack growth rate tests were conducted on eleven compact tension specimens of A588A steel plate to assess the ability of linear cumulative damage models to estimate fatigue life under load-time histories composed of cycles of variable amplitude and mean. Crack opening was monitored using a clip gage and through transmission ultrasonics.
