Power aspects of energy dissipation during plastic deformation in different stressed states. Part
Work of plastic deformation defined as the area under deformation curve plotted on the «load-absolute elongation» coordinates for tension and on the «torque-turning angle» coordinates for torsion has been considered. To obtain adequate results the specific values of work determined by the «stresses-...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Work of plastic deformation defined as the area under deformation curve plotted on the «load-absolute elongation» coordinates for tension and on the «torque-turning angle» coordinates for torsion has been considered. To obtain adequate results the specific values of work determined by the «stresses-relative deformation» diagram have been compared. It is shown that for torsion the observed changes in values of specific work of the deformation are 3−5 times larger than for tension. This is connected with different activation of sliding systems during the deformation resulting in changes of the character of developing processes of generation, redistribution, accumulation and annihilation of crystalline structure defects of the material. |
