| Popis: | This paper is devoted to the study of the laws of the deformation behavior of metals, determined by carrying out standardized uniaxial tensile tests. The distribution of various strength grade metals by strain resistance was analyzed. It was taken into account that in the thermodynamic aspect the deformation process is a dissipative effect. In that regard, the magnitude of deformation work, determined by the area of the tension diagram, serves as a basis for assessing the deformability criteria of metals. It was found, that the normalized specific work of deformation linearly increases with strength. As well as it was established that localization of plastic flow is related directly to the characteristics of the tension diagram under solid deformation. In the applied aspect, the numerical values of the compliance criterion can be used to predict the materials behavior of different strength grade during mechanical processing (metal forming and cutting) or operation. |
