This short report concerns the second part of the work performed in ArGEnCo in order to implement advanced incremental-iterative solution techniques into the finite element code LAGAMINE for geometrical and phys- ical non-linear problems. More specifically, it deals with the implementation of a convergence criterion suitable for material non linearity and the validation of the approach on a Brazilian test on a concrete specimen.
