| To evaluate the stress-strain state and the fatigue life of critical engineering structures developed a model of damaged media (MDM) consisting of three interrelated components: relations defining the elastoplastic behavior of the material, the kinetic equations of damage accumulation and strength criterion damaged material. In order to qualitative and quantitative evaluation of constitutive relations at MDM low-cycle loading conditions evaluated fatigue life of the band with a cut under cyclic loading. Shown that the development version of the constitutive relations adequately reflects the main effects of elastic deformation and the processes of low-cycle fatigue of materials and structures. |
