NUMERICAL MODELLING OF MECHANICAL RESPONSE OF A TWO-PHASE COMPOSITE

摘要

The presentation considers behaviour of two-phase composite material. According to experimental observations (SME imaging) this type of composites can be considered as polycrystals consisting of grains and thin intergranular layers. A representative volume element (RVE) has been analysed taking into account its internal structure. The analysis is carried out using FE technique. The technique is applied to obtain mascroscopic stresses distribution due to initial defects embedded in the intergranular layers of the sample (RVE).
