Brittle‐ductile transitions in polyethylene
Polymer Engineering & Science, 2002AbstractThe failure mode of a number of polyethylenes has been studied under predominantly plane strain conditions. Square section samples, notched on all sides, have been tested in tension to failure over a range of crosshead speeds and temperatures. Integration under the subsequent load displacement curve has allowed the total energy, energy to peak ...

Ductility Transition and Cold Brittleness
Journal of the Physical Society of Japan, 1953The occurrence of the change of fracture from ductile type to brittle one which is often called `cold brittleness' is studied from the standpoint of the stochastic theory. In the present paper failure and fracture processes were treated as reaction rate process.

Brittle failure in compression: splitting faulting and brittle-ductile transition
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1986Abstract The micromechanics of brittle failure in compression and the transition from brittle to ductile failure, observed under increasing confining pressures, are examined in the light of existing experimental results and model studies.

The Brittle-Ductile Transition of Silicon
1987At the preceding workshop 1981 on Corsika one of the authors analysed the early measurements of St. John (1) on the b/d transition of pre-cleaved Si single crystals. The analysis was based on the assumption that dislocations can be easily produced at the crack-tip in an otherwise perfect crystal.

On the brittle-ductile transition pressure
Acta Metallurgica, 1967Abstract A theory for the change from brittle to ductile fracture behaviour with increasing superimposed hydrostatic pressure is proposed, and is extended to account for the effect of temperature on the transition. The theory agrees well with empirical relationships developed previously by other workers, and shows that an effect due to grain size is ...

The brittle-to-ductile transition in silicon
Acta Metallurgica et Materialia, 1993In order to better understand the brittle-to-ductile transition in silicon, details of different experimental and numerical studies are discussed. In the concept of elastical stress intensity factors, experiments with four-point-bending bars are not directly comparable with experiments done with tapered-double-cantilever-beam samples.
