Meanwhile the flow stress increases with the increase of the volume fraction of SiC particles. This study helps establish the constitutive model of magnesium matrix composites and offers theoretic......
Finite Element Analysis of Push-Out Test of SiC Fiber Reinforced Titanium Matrix Composites () 摘要:Based on the interphase layer model and the spring layer model, an improved interface model was developed to evaluate the interfacial shear strength of Titanium matrix composites(TMCs) and to analyze the effects of various parameters on the interfacial properties. The results showed......
