Crack propagation in reservoir rocks in the CO2 storage context
(2014-12-11)
The CO2 capture and storage (CSC) in the deep geological formations is a promising solution to
decrease the undesirable effects of the CO2 concentration in the atmosphere. One of the most
important aspects concerning the ...
Analysis of crack propagation in the wedge splitting test via digital image correlation and finite element analyses
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2019-02-19)
Castable refractories are applied in dangerous environments in which it is unpractical to avoid crack initiation. Therefore, their microstructure is usually complex in order to hinder crack propagation by toughening ...
The effect of the embrittlement on the fatigue limit and crack propagation in a duplex stainless steel during high cycle fatigue
(Elsevier, 2013-09)
In order to evaluate the effects that the “475° embrittlement” produces on the fatigue life during high-cycle fatigue, stress-controlled cyclic loading tests were conducted on a standard duplex stainless steel in two ...
Residual modulus degradation model for woven fabric composite determined by impulse excitation technique
(2020-04-01)
Structural components in the aircraft industries often require geometries that induce stress concentration effects, intensifying fatigue phenomena. When combined with a lack of structural monitoring it may limit composite ...
2d Analysis Of Intergranular Dynamic Crack Propagation In Polycrystalline Materials A Multiscale Cohesive Zone Model And Dual Reciprocity Boundary Elements

Estimation of notch sensitivity and size effect on fatigue resistance
(Elsevier, 2013-12)
This paper addresses the problem of high cycle fatigue resistance associated to notches and the role of short crack propagation in the fatigue notch sensitivity quantified by the notch factor. An integrated fracture mechanics ...
Study of thresholds to burning in surface grinding process
(2005-04-01)
This work aims at finding out the threshold to burning in surface grinding process. Acoustic emission and electric power signals are acquired from an analog-digital converter and processed through algorithms in order to ...

Integrated fracture mechanics approach to analyze the fatigue behaviour of welded joints
(Maney Publishing, 2004-10)
Current fracture mechanics methods for fatigue assessment, including those that consider thresholds for crack propagation, are based on long crack behaviour. The present work is concerned with an attempt to predict the ...
The role of microstructure in fatigue crack initiation and propagation in 9-12Cr ferritic-martensitic steels
(Elsevier, 2014-06)
The present paper presents low-cycle fatigue results about cyclic behaviour, the evolution of the dislocation structure and the nucleation and propagation of microstructural cracks in commercial ferritic-martensitic steel ...
