Effective Elastic Constants of Fiber-eutectics and Transformation Particles Composite Ceramic

摘要：

The composite ceramics is composed of fibereutectics,transformation particles and matrix particles. First,the recessive expression between the effective stress in fiber-eutectic and the flexibility mcrement tensor is obtained according to the fourphase model. Second,the analytical formula which contains elastic constant of the fiber-eutectic is obtained applying Taylors formula. The eutectic is transverse isotropy,so there are five elastic constants. Third,the effective elastic constants of composite ceramics are predicted. The result shows that the elastic modulus of composite ceramic is reduced with the increase of fibers fraction and fibers diameter.
