The finite element analysis (FEA) has become an effective way to numerically simulate strength distribution in a powder metallurgy (P/M) compact. A 2-D Finite element model is carried out to simulate the flow behaviours of green aluminium powder compacts. The complicated case of green aluminium powder makes it is difficult from metalwork point of view to get analytical or empirical model to predict the compacts strength. Therefore, Cold Compression test is simulated using the 2-d model with ABAQUS software for compacted aluminium plate. Moreover, fracture toughness of the compacted aluminium powder is calculated using 2- D J-integral finite element model implemented into ABAQUS commercial. The results are in good agreement with the experimental ones and give a valuable graph decrypting the flow behaviour of the green compacts. The calculated fracture toughness of compacted aluminium powder is nearly
