Numerical Simulation of SHPB Experiment on Dynamic Behaviour of Ceramic Particle Reinforced MMCs
The dynamic behaviour of ceramic particle reinforced metal matrix composites (MMCs) is a key to its application. In this paper, the computational micro-mechanics method (CMM) is used to simulate SHPB experiment of MMCs. The numerical SHPB’s specimen of MMCs is firstly generated by CMM. Then, for verifying the correction of numerical experiment, the Al2O3/6061- T6Al composite is used to carry out numerical experiment, and the Johnson-Holmquist (JH-2) damage model is used to describe the ceramic mechanics behaviour, and a comparison between this numerical method and Unit Cell analytical model is carried out. Lastly, the dynamic behaviour of T6061Al/Al2O3 is investigated by this method.
