Sentence examples for main crack tip from inspiring English sources

It is shown that the velocity of the main crack tip is significantly lower than the one of the cavity edge toward the main crack tip, like in metallic alloys.

The radius of the main crack tip was about 2.5 nm.

Distances between discontinuous nanocracks and the main crack tip were 5 60 nm which depends on the applied tensile loading.

Nanometre scale cracks are initiated discontinuously ahead of the main crack tip in the highly stressed zone.

Interactions between cracks and toughening particles have been identified within the epoxy, particularly: particles de-bonding ahead of the main crack tip, creating a preferential damage path, and the bridging of cracks by un-failed ligaments.

Depending on the local crystallographic orientation of the deformable component of the bimaterial, the model predicts that a brittle backwards growth of the microcrack may occur while the main crack tip remains inert.

In particular, a parametric study in terms of the main characteristic geometric parameters of the laminate is proposed to show the main features of the crack tip behavior.

In these materials tiny microcracks open up to either side of the main crack path ahead of the advancing crack tip.

Moreover, the velocities of the different fronts (main crack, frontward and backward cavity tips) at these nanometric scales is one order of magnitude smaller than the crack tip velocity at the continuum scale.

In this paper, a fatigue life prediction model under various load spectra, using the strain energy density factor approach and the plastic zone size near crack tip as main parameters in calculating effective strain energy density factor, has been proposed.

We focus here on the kinematics of crack propagation by looking at the spatio-temporal evolution of both the tip of the main crack and the cavity ahead.
