Strain characteristics of materials with defects
A. I. Kozinkina Blagonravov Institute of Machine Science, Russian Academy of Sciences, Moscow, 101990, Russia
Abstract:
For uniaxial tension of St. 3 steel, the stiffness-matrix components are determined using a two-dimensional plastic solid model and taking into account the formation and development of anisotropic damage. In order to characterize defect formation, a vector damage criterion is introduced, mictrostructural analysis data are used, and the destruction point is established. Estimates of the elastic moduli and experimental data indicate that the model provides a qualitative description of the real deformation and failure processes of deforming and destruction and can be used to determine the life of materials.
Keywords:
plastic solid, slip systems, elastic moduli, anisotropy, defects.
