The Rate of Set of Metals Subjected To Strain
The writer has, in a preceding paper shown, by reference to experimental researches, in which he had then engaged, that some classes of metals, as ordinary iron and steel, when subjected to strain and distortion by a force exceeding the resistance of the material within the elastic limit, take a set and are stiffened by that act, and exhibit an exaltation of the elastic limit. It was also shown that other classes, like tin, and similarly viscous and ductile materials, exhibit flow and a depression of their limits of elasticity when similarly treated. It was further shown, that the former class when subjected to loads, even approaching their ultimate strength, took a certain set and remained apparently indefinitely without further distortion; while the second class, under very moderate loads, frequently exhibit a gradual yielding, a progressive distortion, until fracture took place, sometimes under stresses which were but a fraction of those which were found required to break such metals quickly, and when time was not allowed for flow to occur.
