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… More >
