Page 5 - The fact that a metal possesses a certain elastic iiinit, tensile strength, elongation and contraction of area when ruptured by once loading, fails to convey an adequate idea of what the same metal will do under circumstances of repeated stresses, or when these repeated stresses are applied in alternate directions. The present investigation pertains to the effects of alternate stresses in opposite directions in which the tensile and...
