The stress - strain relation of the solid phase of sintered iron is calculated for materials with a porosity of 1-30. The deforming stress is calculated with allowance for features of the deformation of the specimens and stress redistribution over their volume connected with transformation of the pore structure in tension. Porosity is determined to have an effect on the curve which describes the strain-hardening of the solid phase. The nature of the effect is discussed in connection with a change which occurs in the stress state in active volumes of materials with different porosities. The laws that determine the dependence of the uniform strain on porosity are also discussed. [ABSTRACT FROM AUTHOR] |
