MEASURING METHOD AND APPARATUS FOR DETERMINING THE STANDARD ELONGATION LIMIT IN A LOAD CONDITION

摘要

P The present invention relates to a measuring method and apparatus for determining the standard elongation limit. /P P It is characterized in that, during continuous deformation, the ratio between any instantaneous elongation due to an elastic variation in shape and the load corresponding to this instantaneous elongation is established and stored, in that '' then, the continuous deformation continuing, we establish and add the relationships between a predetermined constant elongation, the instantaneous elongation mentioned above and the aforementioned instantaneous load, in that we compare the sum obtained with the stored value, and in this that, when the two values are equal, the instantaneous load obtained defines the standard elongation limit. /P P It relates to the metallurgical field. /P
