Experimental and simulation study on Ⅰ-Ⅱ mixed-mode fatigue crack growth of TC4-DT welded joint

Journal of Aeronautical Materials, 2020
The crack growth in the structure shows the complex Ⅰ-Ⅱ mixed-mode under the combined tensile and shear fatigue loading. It is of great significance to understand its growth law for evaluating the fatigue life of structures accurately.

Micromechanisms of short fatigue crack growth in an Al-Si piston alloy [PDF]

, 2014
The short fatigue crack growth behaviour of a model cast aluminium piston alloy has been investigated. This has been achieved using a combination of fatigue crack replication methods at various intervals during fatigue testing and post-mortem analysis of

Size effects on residual stress and fatigue crack growth in friction stir welded 2195-T8 aluminium - Part I: Experiments [PDF]

, 2011
Residual stress fields were measured in three different sizes of Compact-Tension (C(T)) and eccentrically loaded single edge notch (ESE(T)) specimens containing transverse or longitudinal welds. The effect of size on residual stress profiles was studied.

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

, 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 ...

Influence of woven ply degradation on fatigue crack growth in thin notched composites under tensile loading [PDF]

, 2010
This paper deals with the fatigue of the through the-thickness crack propagation in thin notched composite laminates made of two glass woven plies. It highlights the different crack growths between warp and weft directions of the woven ply.

Modeling of creep-fatigue interaction effects on crack growth at elevated temperatures

MATEC Web of Conferences, 2018
The well-known load frequency effect on creep-fatigue crack growth is explained by the interactions between fatigue and creep loading and is quantified using the concept of plasticity-induced crack closure.
