Fatigue crack growth in notched specimens: a numerical analysis

open access: yesFracture and Structural Integrity, 2019
Fatigue crack growth (FCG) is linked to irreversible and non-linear processes happening at the crack tip, which explains different problems observed in the use of da/dN-?K curves. The replacement of ?K by non-linear crack tip parameters, namely the crack

An inverse method for evaluating weld residual stresses via fatigue crack growth test data [PDF]

open access: yes, 2010
This paper presents an inverse method for calculating the thermal residual stresses in welded specimens via measured fatigue crack growth rates. Firstly, fracture-mechanics superposition law has been used to extract the stress intensity factor due to ...

Evaluation of the intrinsic crack growth rates of weld joints [PDF]

open access: yes, 2011
A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...

Novel Characterizations of Effective SIFs and Fatigue Crack Propagation Rate of Welded Rail Steel Using DIC

open access: yesMetals, 2023
The fatigue crack growth-rate test of rail head, waist, and bottom material for U71Mn welded rail was carried out. Digital image correlation (DIC) was used to capture the full-field displacement.

Surface Crack Shape Evolution Modelling using an RMS SIF approach [PDF]

open access: yes, 2010
The majority of fatigue cracks in thick plate and tubular sections in structural components are two-dimensional surface cracks having significant propagation lives before becoming critical.

Study on the Influence of the Gurson–Tvergaard–Needleman Damage Model on the Fatigue Crack Growth Rate

open access: yesMetals, 2021
The fatigue crack growth (FCG) process is usually accessed through the stress intensity factor range, ΔK, which has some limitations. The cumulative plastic strain at the crack tip has provided results in good agreement with the experimental observations.

The effect of a capillary bridge on the crack opening of a penny crack [PDF]

open access: yes, 2016
Young's relation is based on the equilibrium of horizontal components of surface tensions for a liquid droplet on a "rigid'' substrate without addressing the substrate deformation induced by the net vertical component of surface tensions.
