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 ...

An approximate, analytical approach to the `HRR'-solution for sharp V-notches [PDF]
International Journal of Fracture, 2002 The well-known so-called `HRR-solution' (Hutchinson, 1968 and Rice and Rosengren, 1968) considers the elasto-plastic stress field in a power-law strain hardening material near a sharp crack. It provides a closed form explicit expression for the stress singularity as a function of the power-law exponent `n' of the material, but the stress angular ...

Mode II brittle fracture: recent developments [PDF]
Fracture and Structural Integrity, 2017 Fracture behaviour of V-notched specimens is assessed using two energy based criteria namely the averaged strain energy density (SED) and Finite Fracture Mechanics (FFM). Two different formulations of FFM criterion are considered for fracture analysis. A

Mixed Mode Fracture Investigation of Rock Specimens Containing Sharp V-Notches
Materials, 2022 This work aims to assess both experimentally and analytically the fracture behavior of rock specimens containing sharp V-notches (SV-notches) subjected to mixed mode I/II loading. To this end, firstly, several mixed mode fracture tests were conducted on Brazilian disk specimens weakened by an SV-notch (SVNBD sample), performed in their corresponding ...

On the notch sensitivity of cast iron under multi-axial fatigue loading [PDF]
Fracture and Structural Integrity, 2014 This work deals with the notch sensitivity of sharp notches under multi-axial fatigue loading. The main discussion concerns the differences in notch sensitivity at high cycle fatigue regime, between tensile, torsional and combined loading.
