A discrete model for the estimation of the effect of random voids on the structural properties of a two-dimensional
solid is presented. Triangular void cells are used to simulate randomly located micro-cracks.
The proposed model is solved usingCell Method, a recent numerical method that allows a direct discrete formulation
of balance equations. Both heterogeneities of the structure and stress concentrations due to voids distribution are
taken into account by the model. Followingan introduction, some aspects of Cell Method for plane elasticity that are
relevant for this paper will be briefly recalled and results from simulations in the elastic field will be discussed. Next, the
proposed model will be extended to plastic field and more simulations will be presented. Results show that this model
can be successfully employed to assess the structural response of a 2D solid with randomly distributed voids.
