DETERMINING THE PLASTIC STRAIN RESISTANCE OF METALLIC MATERIALS ON AN AUTOMATED PLASTOMETRIC COMPLEX
An overview of the main methods and equipment used to determine plastic strain resistance under compression tests is given. A testing technique for solid and build-up cylindrical specimens, as well as square cross-section ones, implemented on an automated plastometric complex is described in detail. The results of the evaluation of strain resistance obtained with the application of the developed methods for a large number of steels and alloys are presented.
