论文简介
Interphase effect on the strengthening behavior of particle-reinforced metal matrix

composites is numerically investigated, in which the stiffness, thickness and

debonding location of interphase are considered. Embedded cell model and finite

element method are used in analysis. The numerical results indicate that hard and

soft interphases result in the increase and significant decrease of the strength of

composite, respectively. Location of debonding has quite different effects. Pole

debonding results in a remarkable decrease of the overall strength of composite,

while equator debonding results in a slight decrease of the strength of composite.

Debonding between the interphase and matrix has more significant effect than that

between the interphase and particle.
