BrittlenessArticle about Brittleness by The Free Dictionary

The brittleness of a material becomes more evident as the stress concentration becomes greater. Thus, brittleness must be considered with respect to the conditions under which the material is used. A condition for the growth of a brittle crack is a breakdown in the equilibrium between the energy of elastic deformation released in the process and the increase in the total surface

Research on single-point diamond fly-grooving of brittle

Then, a mechanics-based model was proposed to describe the material stress condition under the diamond tool. The machining parameters were incorporated into the model to understand fly-cutting behavior. It was shown that the fly-cutting technique is highly suitable for the ductile removal of brittle materials by generating large compressive pressures in the chip formation zone. This condition

What is a Brittle Fracture? Definition from Corrosionpedia

A brittle fracture is a breakage or cracking of a material into discernible parts, from which no deformation can be identified (a clean break). It is characterized by rapid crack propagation with low energy release and without significant plastic deformation. The fracture may have a bright granular appearance. The fractures are generally of the flat type and chevron patterns may be present.

Brittle and Ductile Deformation ClassZone

Generally, rocks respond to stress in one of two ways they break, or they bend. When a rock breaks, it is called brittle deformation. Any material that breaks into pieces exhibits brittle behavior. When rocks bend or flow, like clay, it is called ductile deformation. What conditions do you think would be necessary for rocks to respond like clay?

And if the concentration gets too great, the material will fail, creating a crack that can propagate into a fracture. "This ability to slip without letting go is the key to ductility, and to avoiding brittle fracture in plastics," notes Rutledge. A key factor in the molecules' ability to slip and slide is temperature. Specifically, there

2Ductile to Brittle TransitionSchool of Materials

The ductile to brittle transition temperature is strongly dependant on the composition of the metal. Steel is the most commonly used metal that shows this behaviour. For some steels the transition temperature can be around 0°C, and in winter the temperature in some parts of the world can be below this. As a result, some steel structures are very likely to fail in winter. Example of Brittle
