Show more >The damage and crack resistance improvement of bioactive glass is of prime importance, particularly when applied to the repair of load-bearing bones. The present contribution is focused on the prediction of damage mechanisms and crack resistance under uniaxial compression of bioactive glass matrix composites reinforced with a particulate phase. In order to characterize the effects of voids and particles on the damage mechanisms and the macro-response, a two-step homogenization is performed by considering the two phases existing at two different scales: micro/meso through the homogenization of the porous matrix and then meso/macro through the periodic micro-field approach. The damage in the bioactive glass matrix is computed via an anisotropic stress-based damage model, implemented into a finite element program. Failure resulting of excessive damage accumulation in the bioactive glass matrix is predicted by a critical damage criterion combined with a vanishing element technique. The implication of particles in the toughening mechanism as well as the damage and crack resistance improvement in this class of porous biomaterials is highlighted via a parametric study using the proposed numerical model.Show less >
