Тест на спиральное удлинение с позиции механики деформации

Abstract

The analysis of a standardized methodology for determining the rate SEN spiral elongation of copper wire. Any inconsistency in the wording of the standards. The tests of the wire in a variety of definitions SEN. Asked to verify compliance with the standards set by the creation of stress, as well as specify the degree of strain that has accumulated in the metal. Revealed that the use of high-temperature annealing of copper leads to the rising prevalence of spiral elongation and increases its stochastic value. Describes the state of stress that occurs in the experiments, and analyzed its role in the formation rate SEN.
