Investigations of crack-dislocation interactions ahead of mode-III crack

Materials Science and Engineering: A, 2015
Abstract Transmission electron microscopy was employed to investigate the configuration of dislocations emitted by a sharp crack in Al 1100 and Ni base superalloy in part to understand the role of different stacking fault energies. A dislocation free zone and a plastic zone were observed ahead of the cracks in both cases with different dislocation ...

Loading Mode (Mode I/Mode III) Testing for Stress Corrosion Cracking

1984
The use of loading mode variation (Modes I and III) to identify the mechanisms of stress corrosion cracking is reviewed and evaluated, and some recent results on 7075 and 7090 aluminum are presented. It is concluded that the conventional interpretation (that anodic dissolution dominates when results in Modes I and III are similar, and hydrogen ...

Differences Between Mode I and Mode II Crack Propagation

Pure and Applied Geophysics, 2006
Although mode I and mode II crack propagation show many similarities, in particular when analysed by linear elastic fracture mechanics, they differ significantly in the micro-structural behaviour. These differences, which are clearly noticeable in the fracture surface morphology, lead to fundamental differences in the macroscopic behaviour.

Mixed Mode Fatigue Crack Growth in a Center-Cracked Panel

2003
Evaluate the initial fatigue crack growth rate for a 20 mm centre crack in a thick wide plate. The crack is oriented at an angle of 45° to the direction of loading. The plate is subjected to a constant amplitude fatigue loading from 0 to 100 MPa. Material properties: E = 210 GPa, v = 0.25.
