Notch Effects in Fatigue and Fracture
Abstract The notch effect in fracture is characterised by the fact that the critical
gross stress of a notched structure is less that the critical net stress which acts on
the remaining ligament area under the notch tip. The notch effect in fracture is ...

Fatigue Assessment of Welded Joints by Local Approaches
The double fillet weld which runs around the end of the flange reveals
approximately the same notch effect at this point in the three orthogonal sections
(Kf = 2.7, 3.3, 3.3). A particularly severe notch effect occurs at the root face of the
...

Fatigue of Structures and Materials
7.4 Notch effect under cyclic torsion The main fatigue loading cases are cyclic
tension, cyclic bending and cyclic torsion. Differences between notch and size
effects under cyclic tension and cyclic bending are not fundamentally different for

METAL FATIGUE: EFFECTS OF SMALL DEFECTS AND NONMETALLIC ...
3.1 Notch Effect 3.1.1 Effect of Stress Distribution at Notch Roots It has been said
that 80–90% of fracture accidents are caused by fatigue. Investigation indicates
that almost 100% of these fractures start from the sites of stress concentrations at
...

Temperature-Fatigue Interaction
Notch effect in fatigue has been studied quite extensively and there are reliable
procedures for its estimation; see e.g. [1]. Notch effect in creep has been also
studied by a number of investigators, nevertheless there is still no generally ...
NOTCH EFFECT ON FATIGUE STRENGTH OF METALLIC MATERIALS ... In
considering the reliability design of machine elements, the notch effect on the
fatigue strength must be taken into account because of shape discontinuity of
actual ...

Design and Analysis of Fatigue Resistant Welded Structures
fa. K..='—'"e= Q . (83). 1: a Q arc tan A statement worthy of note, drawn from these
equations, is that the notch effect of the shallow notch, after subtracting the basic
stress state, is only half as large for shear loading as for tensile loading.

Thermal Fatigue of Metals
4.5 NOTCH EFFECT The effect of surface roughness is less appreciable in
thermal fatigue than in isothermal fatigue at ambient temperatures, which is
illustrated blow (Dulnev and Kotov, 1 980). The decrease in value of the average
surface ...

Fracture and Fatigue Emanating from Stress Concentrators
The difference between experimental values of critical gross strain and
theoretical values gets from equation (1) characterises the so called notch effect.
The notch influence is strongly related not only to the dimensions of the notch but
also to ...
