Method of arresting crack growth for application at a narrow working space
Mechanical Engineering Journal, 2014 The many fracture accidents in engineering applications are related to fatigue crack initiation and growth. Therefore, the inspection of fatigue crack initiation and the arrest of crack growth are very important for the safe operation of a machine and ...

ON CRACK CLOSURE IN FATIGUE CRACK GROWTH
, 1978 A brief review of the various forms of closure is given, and the relative importance of plasticity-induced closure and roughness-induced closure is considered. On the basis of the lack of a thickness effect and an insensitivity to R in the absence of closure it is concluded that plasticity-induced closure plays a relatively minor role in affecting the ...

Elevated temperature crack growth [PDF]
, 1984 Critical gas turbine engine hot section components such as blades, vanes, and combustor liners tend to develop minute cracks during early stages of operations. The ability of currently available path-independent (P-I) integrals to correlate fatigue crack

Crack growth criteria and crack tip models
, 1988 Summary: The current status of crack tip characterizations is reviewed. Several unresolved areas for further research are identified. Singular fields for stationary and moving crack tips in different nonlinear materials are reviewed and special emphasis is put on the extension of the region where these fields dominate.

Prediction of fatigue crack-growth patterns and lives in three-dimensional cracked bodies [PDF]
Fatigue crack growth patterns and lives for surface cracks, surface cracks at holes, and corner cracks at holes in three dimensional bodies were predicted using linear-elastic fracture mechanics concepts that were modified to account for crack-closure ...

Understanding fast macroscale fracture from microcrack post mortem patterns [PDF]
, 2011 Dynamic crack propagation drives catastrophic solid failures. In many amorphous brittle materials, sufficiently fast crack growth involves small-scale, high-frequency microcracking damage localized near the crack tip.

Short crack initiation and growth at 600 °C in notched specimens of Inconel718
, 2003 The natural initiation and growth of short cracks in Inconel®718 U-notch specimens has been studied at 600 °C in air. U notches were introduced through broaching, and hardness traces and optical microscopy on cross-sections through the U notch broaching ...
