Abstract

System of measurement of the perimetrical variation in tests of materials.This invention concerns a system of measurement capable of determining the perimetrical variation that a certain section of a test tube undergoes during the tests of mechanical characteristics of materials. The devised system of measurement is based on coiling a thread around the section of the test tube whose perimetrical evolution is to be determined. In order to ensure close contact between test tube and thread, it is necessary to apply to it a certain tension, T, at its free ends. Thus, the separation of the free ends of the thread, D1, constitutes the perimetrical variation of the analysed section.
