Hydrogen Influence on Mechanical Properties in Pipeline Steel
Subsea power cable sheathing: an investigation of lead fatigue performance
Hydrogen Influence on Mechanical Properties in Pipeline Steel - state of the art
The state-of-the-art report consist of an overview and a summary of the mechanical behaviour of pipeline steels (in the range of X42-X70) when exposed to electrochemical charging and gaseous hydrogen environment. Experimental data from tensile-, fracture -and fatigue tests in air and hydrogen enviro...
Small and Full-Scale Fatigue Testing of Lead Cable Sheathing
Room temperature creep mechanism of a Pb-Sn-Sb lead alloy
Strain controlled medium cycle fatigue of a notched Pb-Sn-Cd lead alloy
Low-temperature fatigue life properties of Aluminum butt weldments by the means of the local strain energy density approach
Hydrogen informed Gurson model for hydrogen embrittlement simulation
Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the same trend dependent only on stress triaxiality, in other words, the effects of...
Hydrogen enhanced fatigue crack growth rates in a ferritic Fe-3 wt%Si alloy and a X70 pipeline steel
It is well known that ferrous materials can be damaged by absorption of hydrogen. If a sufficient quantity of hydrogen penetrates into the material, static fracture and the material's fatigue performances can be affected negatively, in particular causing a reduction in the material crack growth rate...
