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 ...

I DESCRIBED recently a form of hardness micro-tester which permits light loads to be applied to a diamond indenter of pyramidal form as a means of determining the hardness figures of minute ...

"This discovery is expected to serve as a fundamental theory for describing the plastic deformation of crystalline materials, opening the way for a wide range of applications in material science ...

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 ...

Watch MSE Solder Creep Wire Drop video The load applied to the wire (4.8 kg) is only about one tenth of the load required to get immediate plastic deformation. The experiment shows, however, that ...

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