| Abstract: | The residual stress and its influence on the toughness of ceramic matrix-metall particle composites arc studied in this paper. It is shown that the bridging stress of metall particles has been strengthened by the residual stress, which has some contribution to the toughness increment. Finally the residual stress of two-phase composites is derived using Eshelby method, and the theoretical analysis provides basis for further material toughening design. |
