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

Determination of Residual Stress Distributions in Autofrettaged Thick Cylinders [PDF]
, 2008 High pressure vessels such as gun barrels are autofrettaged in order to increase their operating pressure and fatigue life. Autofrettage causes plastic expansion of the inner section of the cylinder – setting up residual compressive stresses at the ...
