A globally convergent numerical algorithm for damaging elasto-plasticity based on the Multiplier method
TL;DR: In this paper, a new method for the solution of equilibrium problems based on a F.E. displacement formulation is proposed, which is globally convergent as opposed to the classical Lagrangian method that presents only local convergence.

Meso-scale simulation of concrete multiaxial behaviour
TL;DR: In this paper, a new meso-scale model of cementitious materials is proposed, based on a random method that allocates at each Gauss point of the finite element discretisation of the Representative Volume Element a specific phase of the mixture: aggregate, mortar and void.
