In determining the transition from brittle to ductile behavior, temperature, pressure, deformation rate, and material composition are important. Caution: Crustal rocks may exhibit ductile behavior ...

Elastic deformation continues until the yield stress of the material if it is ductile, after which the material plastically deforms. A brittle material fractures before any plastic deformation occurs ...

In a semi-brittle state, rocks exhibit a combination of brittle and ductile deformation, which is the process where rocks change shape permanently by "flowing" or "bending" under stress.

Because of their very large molecular weight (~ 10 6) polymers behave differently from the low molecular weight metals during plastic deformation leading to a ductile fracture. The top diagram shows a ...

These dislocations are defects that allow atomic rearrangement and enable deformation ... which makes them ductile. “The way to improve plasticity for ceramics is to nucleate abundant ...

The book begins with discussions of cyclic deformation and fatigue crack initiation in monocrystalline and polycrystalline ductile alloys as well as in brittle and semi-/non-crystalline solids. Total ...
