A new article based on the algorithm and code implemented by E. Tanné in his thesis (Tanné, 2017) has been accepted in Computer Methods in Applied Mechanics and Engineering< >(Brach, Tanné, Bourdin, & Bhattacharya, 2019).
One of the interesting features of this paper is the identification of pinning of cracks due to the interaction of plastic and fracture dissipation in a homogeneous material!
Crack, plastic strain and stress evolution between two successive time steps showing pinning of a crack tip in a homogeneous elastic - perfectly plastic material.
