| Abstract: |
| The size dependent damage strain distribution of eutectic composite ceramic with eutectic interphase is studied.By the micro-structure characteristics of composite ceramic with eutectic interphase,the local stress field distribution of three-phase element in eutectic composite ceramics is suggested to determine the local strain field distribution of the eutectic rod.The emerging cause of damage behavior of the eutectic ceramic rod is interpreted and damage variables is accounted for determining the local strain field distribution of the eutectic rod with damage behavior by using three-phase model method.On the basis of the relation between local strain field and fiber diameter,the size dependent damage strain field of the eutectic ceramic rod is analyzed.The results show that the damage strain fields in matrix,interphases and fiber of eutectic composite ceramics with eutectic interphase are dependent on the diameter of fibers. |
