Abstract The Bauschinger Effect (BE) impact on
KIN– the combined, Mode I, 3-D Stress Intensity Factor
(SIF) distributions for arrays of radial, internal, surface
cracks emanating from the bore of a fully or partially
autofrettaged thick-walled cylinder is investigated.
A in-depth comparison between the combined SIFs for a
“realistic” - Bauschinger Effect Dependent Autofrettage
(BEDA) and those for an “ideal” - Bauschinger Effect
Independent Autofrettage (BEIA) is performed. The 3-
D finite element (FE) analysis is performed employing
the submodeling technique and singular elements along
the crack front. Both autofrettage residual stress fields,
BEDA and BEIA, are simulated using an equivalent… More >
