This measuring apparatus for determining the limit of elongation in a standard load condition

摘要

P the present invention relates to a process and a measuring apparatus for determining the limit of elongation standard. / p & & p & it is characterized in that, during the continuous deformation, it is established and the ratio between an instantaneous any elongation due to a variation of elasticity of shape and the load corresponding to this elongation, which then, the continuous deformation continues, and is added, the elongation ratios between a predetermined constant, the abovementioned instantaneous and the instantaneous load, in that it compares the sum obtained with the stored value, and in that, when the two values are equal, the instantaneous load obtained defines the boundary of elongation standard. / p & & p & it relates to the field of metallurgical. / p
