Fatigue growth rate of inclined surface cracks in aluminum and titanium alloys
In this paper the fatigue crack growth tests were carried out on surface-crack tension (SCT) specimens, made of 7050 and Ti6Al4V alloys, with initial semi-elliptical surface cracks.

Effect of loading mode and impact velocity on crack propagation of coal
In order to study the influence of loading mode and impact velocity on coal crack propagation law, asymmetric semi-circular bend specimens were used to develop test and numerical simulation with multiple impact speeds under three loading modes of mode Ⅰ,

Propagation behavior of two collinear mode Ⅰ cracks driven by explosive gas
In smooth pre-splitting blasting, two collinear cracks extending opposite to each other between adjacent holes will first avoid each other and then attract each other, resulting in crack propagation path that often presents hooked or butterfly-shaped ...

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