Abstract: We present a continuum phase field theory of ductile fracture coupled with a recently proposed model of two-temperature thermoviscoplasticity at finite strains. A geometric approach to diffusive crack modelling based on a so-called balance of regularized crack surface is used to obtain the evolution of the crack phase filed. Thermoviscoplastic behaviour of the bulk is modelled through a dislocation density evolution. Coupling of these two is established via bulk response driving the crack which in turn degrades the bulk properties. © 2017 ICF 2017 - 14th International Conference on Fracture. All rights reserved.
