METHOD FOR DETERMINING FLUIDITY FORCE DURING TENSILE TESTS OF WIRE SPECIMEN

摘要

The invention relates to testing technique, namely to audio opredele1 methods of mechanical properties of materials. The aim of the invention is to improve the accuracy of determining the force at the onset of plastic deformation in the local area of ​​the wire sample. As a parameter indicative of deformation, electrical resistance of the sample used. yield force is determined at the time of unbalance Wheatstone bridge, which shoulders are adjacent portions of the working part of the specimen. 1 ZP f-ly.
