Sentence examples for for large cracks from inspiring English sources

The 24 h immersion of fresh cracks in mortars in calcium lactate or calcium gluconate solutions increased the self-healing kinetics for large cracks.

The growth of small cracks initiated at the surface coincided with the FCP characteristic after allowing for crack closure for large cracks, but the operative fracture mechanisms were different between small and large cracks.

The relationship between FCP rate and stress intensity factor range for large cracks consisted of two sections with different slopes due to the transition of the operative micromechanisms of fracture.

Further, the minimum stress ratio R at which the analyzed cracks can propagate seems to be about 0.6, for which the threshold for large cracks is about 2.7 MPa m1/2.

Thus, fatigue limit associated with natural flaws is estimated from FCG threshold experimentally determined for large cracks under the assumptions that (1) similitude on the FCG behavior of small and large cracks applies for cemented carbides, and (2) critical flaws are the same, in terms of nature, geometry and size, under monotonic and cyclic loading.

The modifications involve: a material constant that provides a transition from stress control of fatigue crack growth for small cracks to stress intensity factor control for large cracks, a plastic zone size correction, and consideration of crack closure in the wake of a newly formed crack.

It is shown that the predicted crack propagation lives using the un-patched surface fracture parameters are too conservative for large crack growth values.

For larger cracks, Tim Carter, the founder of askthebuilder.com, a home improvement site, said additives or bonding agents should be used to help a large patch stick to the old concrete.

Moreover, fatigue crack growth rates of small cracks in these alloys were found to be greater than those of large cracks for the same stress intensity factor range.

Whilst fracture mechanics based concepts have been found to be a good tool for predicting the growth of large cracks, many researchers have questioned the validity of the similitude hypothesis in Region I.

This effect was accentuated for the measured thresholds of microstructurally-small surface cracks; such small-crack, mixed-mode ΔGTH thresholds not only displayed a minimal influence of mode-mixity but were up to two orders of magnitude smaller than those for corresponding large cracks at the same load ratio and mode-mixity conditions.
