Crack shapes and crack driving force distributions for naturally growing fatigue cracks

Mikel Escalero et al.

Summary: Extensive literature suggests that fatigue cracks tend to reach a stable stage with a quasi-constant crack shape under the influence of an iso crack driving force (CDF) distribution. This study investigates fatigue crack growth using a finite element simulation approach and a theoretical analysis. The results contradict previous findings and demonstrate that naturally growing fatigue cracks converge towards a quasi-constant crack-shape regime, influenced by a non-iso CDF distribution dependent on material properties and the stable crack shape.

Role of Fractal Effect in Predicting Crack Initiation Angle and Its Application in Hydraulic Fracturing

Xin Liang et al.

Summary: The prediction of crack initiation angle is an important issue in hydraulic fracturing. This study utilizes fractal dimension to represent the geometric irregularity of fractures, and derives three fractal fracture criteria to judge the crack initiation angle. Experimental results show that the energy-based fractal criterion prediction is the most accurate, and the predicted initiation angle considering the crack fractal effect is more consistent with the experimental data. Parametric sensitivity analysis reveals that the initiation angle of hydraulic fractures increases with the crack fractal dimension, which can be amplified with the increase of in situ stress difference or decrease of the Biot coefficient.

Crack initiation considering the possible stress acting on the crack surface under uniaxial tension or compression

Xin Lv

Summary: In classical fracture mechanics theory, it is believed that crack surface is open under tension and closed under compression. However, under small angle uniaxial tension, the stress field at crack tip is small because the crack surface may also be closed. This paper considers both the far-field stress and the possible stress acting on the crack surface, and derives the stress field at crack tip. The crack initiation angles of open or closed cracks under uniaxial tension or compression are studied based on the generalized maximum tangential stress criterion.

Study on the stress field concentration at the tip of elliptical cracks

Yan-Shuang Yang et al.

Summary: Holes and defects in rock materials have a significant impact on their mechanical properties and failure mechanism. Cracks often appear in the form of flat ellipses in natural rock mass. Numerical simulation results show that as the ratio of long to short axes of the elliptical fracture increases, the strength and elastic modulus of the rock decrease, the Poisson's ratio increases, and the number of micro-cracks in the rock decreases.
