Machine learning based crack mode classification from unlabeled acoustic emission waveform features

Cement and Concrete Research, 2019
As the cracking mode (tensile or shear) of a crack is related to the underlying physical mechanisms, crack mode classification is a very useful method to identify the damage state of a structure for proper maintenance to enhance structural safety and ...

Fatigue crack propagation modes: plastic deformation mode and damage accumulation mode

International Journal of Fracture, 2020
To define the fatigue crack propagation mode for the prediction and classification of the experimental results based on its evolution mechanism, successive mesoscopic observations of a fatigue process under pure cyclic mode II loading are performed. Thus, damage accumulation, which is considered to be a vacancy accumulation, is found to be a mechanism.

Experimental and numerical investigation of mixed mode I + II and I + III fatigue crack growth in S355J0 steel

International Journal of Fatigue, 2018
This paper presents the results of an experimental investigation about fatigue crack paths and fatigue crack growth on S355J0 steel subjected to I + II and I + III mixed mode conditions both under load ratios R = 0 and 0.1 and different mode mixities. In

Mixed Mode Cracking in Layered Materials

1991
The aim is to pull together recent work on the fracture of layered materials. The potential application of fracture mechanics of layered materials ranges over a broad spectrum of problem areas. Included are: protective coatings, multilayer capacitors, thin film/substrate systems for electronic packages, layered structural composites of many varieties ...

Effect of polypropylene fibers on the mode I, mode II, and mixed-mode fracture toughness and crack propagation in fiber-reinforced concrete

, 2020
Concrete is the most commonly used material in civil engineering and also the most conventional and cheap material available in the market. Concrete cracking and fracturing may cause irreparable damages to concrete structures.

Cracking characteristics of mixed mode dislocations near a lip-like mode crack

Theoretical and Applied Fracture Mechanics, 2009
This work is concerned with the cracking characteristics of mixed mode dislocations near a lip-like mode crack, stress intensity and strain energy density factor are obtained by using conformal mapping, singularity analysis and Cauchy integrals. Shielding effect generated by screw dislocation near a lip-like mode crack decreases with the increment of ...

Mixed-Mode Crack Propagation

2021
Griffith’s instability criterion regards structural configurations with cracks set orthogonally to the direction of the maximum principal stress. In actual fact, this symmetrical mode of applying a load to the defect occurs only in fracture toughness tests, whereas the fractures occurring in structures when they are in service indicate how the ...
