An inverse method for evaluating weld residual stresses via fatigue crack growth test data [PDF]

open access: yes, 2010
This paper presents an inverse method for calculating the thermal residual stresses in welded specimens via measured fatigue crack growth rates. Firstly, fracture-mechanics superposition law has been used to extract the stress intensity factor due to ...

Fatigue testing system with a helium recondenser and fatigue tests.

open access: yesTEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1986
A liquid helium temperature fatigue testing system was developed at the National Research Institute for Metals, Tsukuba Laboratories. The system is equipped with a recondenser installed in the test machine cryostat. Helium mist is transferred to the recondenser from the refrigerator, and the evaporated helium gas in the cryostat is recondensed into ...

Probabilistic fatigue life prediction of metallic components based on continuum damage mechanics

open access: yesXibei Gongye Daxue Xuebao, 2021
Based on continuum damage mechanics, a probabilistic method of predicting high-cycle fatigue life for metallic components is proposed. First, macro-meso two-scale stress-strain equations are established by combining Eshelby-Kroner localization law and ...
