Originální abstrakt
The contribution deals with numerical simulation of response of the open cell ceramic foam to tensile loading and attempts to predict experimental behavior of the foams using numerical FE model composed of beam elements. Models of different structure irregularity (including regular one) are considered and generated using 3D Voronoi tessellation technique. Complete fracture of the model is simulated by iterative FE simulations where in each step, one strut with maximal tensile stress (higher than the material tensile strength) is removed. Critical forces, leading to complete breakage of the foam structure, together with final fracture “surfaces”, are investigated and compared for both regular and irregular structures.
