... the discrete element method (DEM) to explore the fracture mechanics of several hundreds of 2D tessellations composed of rigid “tiles” bonded by weaker interfaces. We explored crack propagation and fracture toughness in Voronoi-based tessellations (to represent intergranular cracking in polycrystalline...

... Weibull theory, and the consequences of a stochastic strength upon the fracture map are outlined. The fracture toughness of brittle hexagonal honeycombs has been modeled by relating the crack tip elastic fields of an equivalent continuum to the stress state within the lattice ( 1 2 ). It was assumed...
