3D modelling of fatigue crack growth and life predictions using ANSYS
Ain Shams Engineering Journal, 2022 This study uses ANSYS mechanical APDL 19.2 to predict crack propagation trajectories and fatigue crack growth at constant amplitude loading. Mixed-mode fatigue life assessment is implemented by the Paris law model for different configuration of modified ...

Equivalent Stress Intensity Factor: The Consequences of the Lack of a Unique Definition
Applied Sciences, 2023 The concept of an equivalent stress intensity factor Keq is used in the study of fatigue crack growth in mixed-mode situations. A problem seldom discussed in the research literature are the consequences of the coexistence of several alternative ...

Crack path selection in orientationally ordered composites [PDF]
Physical Review E, 2020 While cracks in isotropic homogeneous materials propagate straight, perpendicularly to the tensile axis, cracks in natural and synthetic composites deflect from a straight path, often increasing the toughness of the material. Here we combine experiments and simulations to identify materials properties that predict whether cracks propagate straight or ...

Non steady-state intersonic cracks in elastomer membranes under large static strain [PDF]
Journal of Theoretical, Computational and Applied Mechanics, 2021 Dynamic crack propagation in elastomer membranes is investigated; the focus is laid on cracks reaching the speed of shear waves in the material. The specific experimental setup developed to measure crack speed is presented in details.

Chinese Journal of Mechanical Engineering, 2023 To explore the influence of path deflection on crack propagation, a path planning algorithm is presented to calculate the crack growth length. The fatigue crack growth life of metal matrix composites (MMCs) is estimated based on an improved Paris formula.

Crack path tracking from full field measurements: A novel empirical methodology
Strain, 2020 The identification of crack growth models requires the knowledge of the crack path geometry and, in particular, of the crack tip position. The objective of the present paper is to provide a criterion for the detection of the crack tip position regardless
