杨学贵 %A 刘锋 %A 侯耀永 %J 无机材料学报 %D 1998 %I Science Press %X A plane finite element model was established for two-phase ceramics. The residllal stressdistribution in the model was analyzed, and the variation regularity of internal stress along withthe second phase particle's volumetric proporation was given. The effect to residual stress was alsodiscussed, which is caused by the variation of relation between the thermal expansion coefficientsof the matrices and the second phase particles, the difference between interface stress of theoreticalvalue and calculated one was discussed, and some viewpoints of toughness enhanced mechanismfor this composite material were concluded. %K two-phase composite ceramics %K stress distribution %K toughness enhanced mechanism
