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 ...

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 ...

There is no reason at present for supposing that the plastic deformation of transparent crystals differs fundamentally from that of other crystalline substances, and one may reasonably expect that ...
