Plastic deformation refers to a permanent dimensional change after a mechanical or non-mechanical load has been applied. Elastic, and to some extent, viscoelastic strains are recoverable; plastic or ...

At a microscopic level, deformation in polymers involves stretching and rotating of molecular bonds. More commonly, one distinguishes the deformation mechanisms in polymers as brittle, ductile (with ...

A neck is formed in a tensile test specimen when the UTS of the engineering stress/strain curve is reached. Prior to this stress-strain condition the plastic deformation occurs throughout the sample ...

A rubber band undergoes elastic deformation when stretched a little. A metal drinks can undergoes plastic deformation when it is squashed.

Plastic Tupperware is a kitchen staple, but over time, it can become a health and environmental hazard. Learn how to spot ...
