Resistance to fracture of friction welded joints. Friction welded joints of S45C.

open access: yesJournal of the Society of Materials Science, Japan, 1990
In order to determine the requisite value of toughness for friction welded joints on the basis of fracture mechanics, Charpy impact test and fracture toughness test were carried out at various temperatures on the friction welded butt joints composed of carbon steel JIS. S45C and the base metal.The experimental results indicated that the Charpy absorbed

Evaluation of the intrinsic crack growth rates of weld joints [PDF]

open access: yes, 2011
A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...

Comparison between different approaches for the evaluation of the hot spot structural stress in welded pressure vessel components

open access: yes, 2009
Fatigue cracks in welds often occur at the toe of a weld where stresses are difficult to calculate at the design stage. To circumvent this problem the ASME Boiler and PV code Section VIII Division 2 Part 5 [1] uses the structural stress normal to the ...

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 ...
