... In most engineering materials, however, there will also exist a timedependent elastic strain component. That is, elastic deformation will continue after the stress application, and upon load release some finite time is required for complete recovery. This time-dependent elastic behavior is known as ...

Mechanical Properties of Metals
... Ductility: amount of plastic deformation that occurs before fracture - if ductility is high, the material can be deformed by applying stresses. Ex.: gold - if it is low, material breaks first, without significant deformation (material is brittle) - depend on T: at low T many metals become brittle an ...
