SIMPLE JOINT
: An intersection of two or more structural
members. Also applicableto an intersectionof
unstiffenedor ring-stiffenedcylinders.
STEADY STATE
: Generally refers to the periodic response of a
dynamic system after initial starting
transients have decayed to negligible
amplitude.
STRESS CONCENTRATION FACTOR : The ratio of hot-spot stress to the nominal
(SCF)
stress (in neighborhoodof hot-spot) and often
max. mized at geometric discontinueties.
STRIP THEORY
: App” ied to various strip methods to determine
the
bod
hydrodynamic loadings on “ ong slender
es and can account for the effect of
diffracted and radiated waves.
TIG DRESSING
: Tungsten-inert-gas dressing is applied to
remelt the weld toe material to reduce both the
SCF by minimizingdiscontinuitiesand to remove
defects such as slag inclusions.
TRANSFER FUNCTION
: A transfer function defines the unitized
structural response as a function of frequency
(eg ratio of structural response to the wave
amplitude applicable for each frequency).
WELD TOE
: The point of intersection of the weld profile
and parent plate.
WIDE-BAND LOADING
: The smaller stress cycles are interspersed
among larger stress cycles, making the
definitionof stress cycle more difficult. The
use of different counting methods will result
in different fatigue damage predictions.
