Sentence examples for crack initiation point from inspiring English sources

Analyses of the crack initiation point are performed in order to investigate the fatigue failure mechanisms.

Attention is focused on a small part of the groove at a location halfway the circular crack-path, 900 from the crack initiation point.

It is found that the SLJ contains a non-positive geometry at the expected crack initiation point leading to a non-monotonically increasing incremental energy release rate function.

A failure analysis was conducted in order to determine the fatigue crack initiation point and a comparison of that location with the most damaged zone predicted by the numerical analysis is made.

The crack initiation point in high cycle fatigue region depends mainly on weld leg size and incomplete penetration ratio, while the material mismatching between the base and weld metal becomes significant in the low cycle fatigue region.

Detailed finite element analyses that employ the improved ductile fracture model are shown to predict ductile fracture behavior under high stress triaxiality with good accuracy across the mesh sizes, notch radii, and notch degree in terms of ductile crack initiation point, ultimate load point and load-displacement curve.

This can result in less strength improvement because crack initiation points are readily available in the lower defect density glasses.

The effective notch strains were determined at the crack initiation points.

Nanostructure fabrication may substantially enhance the bending strength of glasses with higher defect densities by redistributing stress from the crack initiation points of random defects.

However, glass substrates with lower defect densities are expected to have fewer crack initiation points and thus a lower probability of failure.

In addition, the fractured fatigue specimens were investigated using a scanning electron microscope in order to obtain information about the crack initiation points.
