Finite element model of real structure for particle reinforced composites

A new technique for modeling a real structure of particle reinforced composites is proposed. Complex boundaries of the tungsten alloy SEM photos and concrete photos are fixed and extracted. Then, these figures are transformed into vector-graphs and imported into finite element (FE) program. The FE models of tungsten alloys and concrete are established using a similar method. The fracture process of concrete under compression load is investigated. This new technique for FE model can avoid errors caused by the artificial FE model. The method can thus be used to simulate the mechanical properties of particle reinforced composites under different loads.
