	%X Using finite element method (FEM), the elastic
new strain-concentration factor (SNCF) of cylindrical bars
with circumferential flat-bottom groove is studied. This new
SNCF has been defined under triaxial stress state. The
employed specimens have constant groove depth with net
section and gross diameters of 10.0 and 16.7 mm,
respectively. The length of flatness ao has been varied form
0.0 ~12.5 mm to study the elastic SNCF of this type of
geometrical irregularities. The results that the elastic new
SNCF rapidly drops from its elastic value of the groove with
ao = 0.0, i.e. circumferential U-notch, and reaches minimum
value at ao = 2 mm. After that the elastic new SNCF becomes
nearly constant with increasing flatness length (ao). The value
of tensile load at yielding at the groove root increases with
increasing ao. The current results show that severity of the
notch decreases with increasing flatness length ao.
