Plastic zone size at notch tip in mode I fracture using the modified Irwin’s model and volumetric approach [PDF]
MATEC Web of Conferences, 2021 At crack tip the stress distribution has singularities (i.e the stress intensity is infinite) which is physically impossible. Irwin realised that the stresses at crack tip are finite and subsequently introduced the Stress Intensify Factor(SIF).

Critical applied stresses for a crack initiation from a sharp V-notch [PDF]
Fracture and Structural Integrity, 2014 The aim of the paper is to estimate a value of the critical applied stress for a crack initiation from a sharp V-notch tip. The classical approach of the linear elastic fracture mechanics (LELM) was generalized, because the stress singularity exponent ...

A notch stress method for fatigue life prediction of spot-welded joints [PDF]
MATEC Web of Conferences, 2019 Spot-welded joints are widely used in the construction of vehicle structures and frequently become critical locations for fatigue failure. Hence, it is essential to have reliable fatigue life prediction method for the spot-welded joints during vehicle ...

The fatigue behavior of V-notches in presence of residual stresses: recent developments and future outcomes [PDF]
Fracture and Structural Integrity, 2017 Residual stresses, arising from welding processes or nonhomogeneous plastic deformations, broadly influence the high cycle fatigue behavior of mechanical components. The presence of V-notches leads to singular residual stresses ahead of the notch tip and
