Mathematical models of fine grained materials based on chaotic systems
Original language description
Strongly nonlinear dynamic systems with suitable parametrization can exhibit chaotic oscillations. These irregular oscillations have bounded amplitude but no period. Therefore it is natural to use them for modelling irregularities in microscopic structure of metals. In this work, chaotic sequences of numbers generated by these systems were used for definition of metal grains properties such as their size, misorientation, position on the surface etc. Basic model can meet characteristics of real specimen. It is possible to widely modify the basic model to depict specific qualities of more complicated metal structures. Obtained mathematical model is compared with results of ultra-fine grained titanium sample and carbon steel sample microstructure observation and measurement. © 2014 Institute of Thermomechanics AS CR, v.v.i.
