Humans began creating alloys about 5,000 years ago by combining copper and tin to produce bronze. Since then, alloy design ...

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 ...

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 ...

whose maximum deformation is limited by high tensile and compressive stresses that occur at its top and bottom surfaces and lead to breaking or permanent plastic deformation. In such a bending ...

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.

— In a recent correspondence on hardness 1, several assertions were made, some of which are incorrect and some are misleading. First, the title “What does 'harder than diamond' mean?” ...
