摘要：
By conducting the quasi-static compression and split Hopkinson pressure bar testing Cthe flow strain-stress curves under strain rate range of 0.0001-1000/s and temperature range of normal-400° of different volume fraction SiC particles reinforced metal matrix composite SiCp/6063Al were obtained. The commonly used Johnson-Cook constitutive model in metal materials was applied in this research. And on the basis of it, the influence of volume fraction to flow stress was utilized to establish the equivalent and homogeneous constitutive model. © 2016 Trans Tech Publications, Switzerland.
