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 ...

Influence of fatigue crack wake length and state of stress on crack closure [PDF]
The location of crack closure with respect to crack wake and specimen thickness under different loading conditions was determined. The rate of increase of K sub CL in the crack wake was found to be significantly higher for plasticity induced closure in ...

Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]
, 2013 This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...
