Strength Prediction Model of a Particle-Reinforced Shellproof Ceramic Composite
On the basis of the microstructure of particle-reinforced shellproof ceramic composite, and the intergranular fracture feature, a dislocation pile-up fracture model of the small-particle ceramic composite is developed, the mechanism of formation, growth and coalescence of microcracks. The comp...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | On the basis of the microstructure of particle-reinforced
shellproof ceramic composite, and the
intergranular fracture feature, a dislocation
pile-up fracture model of the small-particle ceramic
composite is developed, the mechanism
of formation, growth and coalescence of
microcracks. The complex effect of the small
particle pull-out and large particle cracking is
concerned, when constructing the crack extension
fracture model. Thereafter, the influence of
particles’ volume fraction and matrix grain diameter
on fracture strength is studied. The experimental
data shows that the proposed strength
prediction model is successful and can be
generally applied. |
