The cohesive frictional crack model applied to the analysis of the dam-foundation joint [PDF]

open access: yes, 2010
The mechanical behaviour of dam-foundation joints plays a key role in concrete dam engineering since it is the weakest part of the structure and therefore the evolutionary crack process occurring along this joint determines the global load-bearing ...

Strain-gradient effect on the crack tip dislocations density

open access: yesFracture and Structural Integrity, 2020
In this study, the influence of a material’s plastic properties on the crack tip fields and dislocation density behavior is analytically and numerically analyzed using the conventional mechanism-based strain-gradient plasticity (CMSGP) theory established

Evaluation of the Effective Stress Intensity Factor Using Thermoelastic Stress Analysis and 2D Digital Image Correlation

open access: yesPhysical Sciences Forum, 2022
In the present work, fatigue crack tip shielding influence is assessed via two full-field optical techniques which are thermoelastic stress analysis and digital image correlation.

Effect of residual stress redistribution on fatigue crack growth pertinent to crack closure and applied load

open access: yesMaterials & Design, 2023
Clarifying residual stress (RS) redistribution and its effect on fatigue crack growth (FCG) is essential to evaluate the fatigue life of a welded joint.

Dynamic Strain Evolution around a Crack Tip under Steady- and Overloaded-Fatigue Conditions

open access: yesMetals, 2015
We investigated the evolution of the strain fields around a fatigued crack tip between the steady- and overloaded-fatigue conditions using a nondestructive neutron diffraction technique.

Crack-tip models by Irwin and Dugdale for hydroxyl-damaged crack-tip zones

open access: yes, 2021
Due to the hydroxyl generation, the silica network ahead of crack tips is damaged. The consequence is a damaged crack-tip zone showing a reduced Young’s modulus. The linear-elastic fracture mechanical treatment by application of stress intensity factors becomes doubtful especially for large zones.

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]

open access: yes, 2011
Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...

The influence of crack tip shielding on fatigue crack propagation [PDF]

open access: yesFracture and Structural Integrity, 2017
The fatigue crack propagation is one of the major problems and of the real concern in the evaluation of the structural integrity of components. This is due to the fact that once a fatigue crack has been detected it is also known its effect on the ...
