fracture

In terms of cutting mechanism, cutting force reaches to the yield limit of the workpiece materials due to the impact and friction [11], the surface material is stripped under the effect of brittle fracture.

13] also described that having an external load that is higher than the critical ductile depth can lead to crack propagation and brittle fractures, and the critical ductile depth can be expressed as follows:

The fiber fracture surface is smooth and there is separation between the matrices, showing that brittle fracture occurred in the specimen.

The investigation concluded that the flow regulator chamber failed via brittle fracture associated with a ductile-to-brittle transition as a result of the exposure of the part to stresses well below the yield strength of the material over an extended period of time.

For the prediction of brittle fracture, the use of TCD requires the knowledge of elastic stress field around stress concentrators (obtained through finite element analysis--FEA) and using two material parameters (L and [[sigma].

Topics covered by the volume's 15 original papers include a new method to determine the Young's modulus of a microcrystal based upon Raman spectrometry, solid-state reaction in an Al-Fe binary system induced by mechanical alloying, thermal behavior of xenon in a refractory metal for gas fast reactor fuel elements, molecular dynamics simulation of brittle fracture in BCC iron, growth kinetics of boride layers, structure and optical properties of magnetron-sputtered SiOx layers with silicon nanoparticles, reaction of iron with amorphous silicon and crystalline silicon for the fabrication of iron silicides, theoretical determination of the pressure-volume-temperature relationship of some alkali halides, and concentration micro-field for lamellar eutectic growth.

The researchers highlight the fact that brittle fracture failure of low-k insulating films remains a problem for the industry, as it affects both manufacturing yields and device reliability.

The word osteoporosis means porous bones and is a condition, where bones gradually become weak and brittle fracture easily.

In the study of the Pb-free bump failure mechanism, it was found that instead of ductile fatigue cracking through the bulk solder bump, the brittle fracture between the bulk solder and UBM was the dominant failure signature after TCT testing.

He led FHWA's forensic investigation of the Hoan Bridge failure in Milwaukee, helped identify the cause of the brittle fracture, and dratted technical guidance to deal with similar problems on other bridges.

Without the brittle fracture, the Titanic might have lasted a couple of hours longer and the nearest ship, the Carpathia, may have got there in time to rescue some of the 1,500 passengers who died.

Common causes of failure include excessive vacuum, excessive internal pressure, foundation failure, brittle fracture, corrosion, change of service, and defects introduced by repairs and alterations.

Foundries should be aware of the factors that affect the strain rate sensitivity of ductile iron and the critical strain rate, which produces the brittle fracture.

Brittle fracture with pure elastic deformation occurs at low temperature or high impact velocity.

In spite of the limitations with regard to its application to soil, brittle fracture theory provides a useful framework within which experimental results can be placed and discussed.
