Complex Network Methods for Plastic Deformation Dynamics in Metals

Plastic deformation of DC04 steel is regarded as a nonlinear, complex, irreversible, and self-organized process. The stress–strain time series analysis provided the possibility to identify areas (quasi-)elastic deformation, plastic necking. latter two regions are most informative. area inelastic reflected by collective, processes that lead formation pores, finally, development microcracks general crack cause sample failure. Network measures for quantitative assessment structural deformations in metals proposed. Both spectral topological network complexity were found be especially According our results, they can used not only classify stages but also, applied precursor material destruction
