For many materials impact tests display a ductile-brittle transition when temperature is lowered. Analyses of the limit moment of notched test pieces and of the stress distribution are given, especially for the Charpy specimen. Testing procedure including instrumented impact testing are described.

Brittle-ductile transition: semi-brittle behavior
Tectonophysics, 1989Abstract In central British Columbia mesoscopic and microscopic deformation mechanisms within metamorphic rocks ranging from greenschist facies through upper amphibolite facies have been examined to evaluate the applicability of single mechanism flow laws at different crustal levels.

Ductile-to-Brittle Transition in MoSi2
MRS Proceedings, 1992We have studied the mechanical behavior of two fine grained MoSi2 alloys containing 0.61 at% (0.19 wt%) and 0.29 at% (0.09 wt%) oxygen, respectively. By preparing these alloys in almost identical fashion, their only difference was their oxygen content. The mechanical behavior was studied by four-point flexure tests in unnotched specimens between 800°C ...

Brittle fracture and the brittle-to-ductile transition of tungsten
Journal of Nuclear Materials, 2003The aim of this paper is to shortly review the experimental observations and the theoretical understanding of the fracture behaviour of tungsten in the brittle and semi-brittle regime. Advances in the understanding of the mechanisms of fracture processes are made by direct comparison of microscopic modelling and carefully designed experiments.

A ductile-to-brittle transition in bone?
Journal of Materials Science, 1974Consideration is given to the possibility that compact bovine femur material undergoes a ductile-to-brittle transition behaviour which is similar in some respects to that which occurs for certain metallic materials. Evidence for this possibility is derived from compressive and tensile bulk strength measurements reported over a range of temperatures and

So far we have been concerned mainly with brittle behaviour culminating in gross brittle fracture. However, under suitable conditions, rock can exhibit ductility. This is an aspect of its behaviour that becomes of central importance in many geologic situations but which may also have relevance in some engineering contexts.

Brittle-ductile transition in rocks
Journal of Geophysical Research, 1968The deformational characteristics of 2 limestones, one gabbro, and one dunite have been investigated as a function of confining pressure. It was found, that friction of these rocks and friction of granite and serpentinite studied elsewhere are nearly identical, and that the brittle-ductile transition pressure is simply the pressure at which the stress ...

Ductile–brittle transition in polymers
Journal of Applied Polymer Science, 1984Tensile experiments on polypropylene and various rubber-modified polypropylenes, conducted over a wide range of temperatures and strain rates, have shown that the ductile–brittle transition in these highly crystalline polymers is strongly affected by both temperature and strain rate.

All thermoplastic polymers, in common with many metals, are capable of undergoing failure either in a brittle manner, like inorganic glasses, or in a ductile manner producing permanent plastic deformation. The temperature at which this transition occurs is the ductile-brittle transition temperature.
