Modeling Dynamic Behaviors of Reticulated Ceramic/Metal Composites (RCMC)
Reticulated ceramic/metal composites (RCMC) are characterized by the ceramic skeleton and metallic matrix both continuous in three-dimensional space,and this special structure makes full use of the ceramic phases high strength and the metal phases toughness.Correspondingly,the deformation and damages mechanisms of RCMC under dynamic load conditions are very complicated and the related studies are quite important.In the current study,the dynamic properties of RCMC are investigated by using finite element methods based on the microstructures of SiC/Al composites.The ceramic/metal interface is induced by employing a constrained-tie-break method to study the effects of interface when suffering from a dynamic impact loads.Effects of the phase distribution,shape,ratio,as well as the size arc systematically analyzed.The methods proposed in this paper would be helpful for predicting the dynamic behaviors of RCMC,and developing new ceramic/metal composites.
