It showed that the volume fraction of particles dispersed in the matrix leads to direct dependencies of the elastic modulus and fracture surface energy; inverse changes in bending strength as well as increasing in art exponential relation with work of fracture and thermal shock damage resistance parameter. The decohesion of the weak interface between particle and matrix may be considered as the origin of toughening. 收稿日期: 1986-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王润泽 刘延伶 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I3/117 1 Hasselman, D.P.H., J.
