Abstract
A Hybrid discrete-continuum Cellular Automata (HCA) approach based on coupling classical thermomechanics and logics of CA-switching to simulate new phase generation and grain growth is proposed. On the basis of the HCA, numerical experiments on thermal-activated recrystallization of pure titanium in the vicinity of crack edges are performed. The 3D cellular automaton is aimed at simulating the behavior of a V-notched specimen region that imitates the crack tip vicinity. Numerical experiments provide calculating heat expansion in the material under study through taking into account thermal stress accumulation and microrotation initiation. The latter gives rise to the generation of new defects and increases local entropy.
