Tensile Strain-Rate Properties of Thorium.

Abstract

An electrohydraulic tensile testing machine was used to determine the effect of s t r a i n rates between 0.01 and 200 sec-1 on the yield point, tensile strength, breaking strength, and ductility of .thorium. Upper and lower yield stresses, tensile strength, and the breaking strength were observed to increase w i t h * increasing strain rate, even at t h e lower rates. Ductility was found to be only .slightly decreased with increasing strain rate.
