This paper examines the effect of the yield criterion of the matrix on brittle fracture of the fibre in continuous fibre reinforced metal matrix composites subjected to tension in the direction parallel to the fibres. It is assumed that the matrix obeys quite a general isotropic yield criterion. An approximate approach to predicting the tensile load at which the fibre breaks previously proposed in the literature is adopted. It is shown that this tensile load is practically independent of the yield criterion of the matrix. This is a great advantage for engineering applications since an analytic solution is available in the case of Tresca yield criterion. This solution can be used for a wide range of matrix materials with no loss of the accuracy of the prediction of the tensile load at which the fibre breaks.

“…[1,2] The reinforcement/matrix interface is formed during the preparation process by the interactions of the reinforcement and the matrix, such as chemical reaction and element diffusion. [3][4][5] The mechanical properties of the PMMCs are determined by the shape, distribution and volume fraction of particles, and the materials characteristics of the matrix and particles.…”

“…They can increase the strength and modulus, but significantly sacrifice the ductility. [1,2] Wang et al studied the Mg-Li matrix composites strengthened with inter-metallic compound YAl 2 . [3,4] They found that using YAl 2 as reinforcement could effectively increase the composite strength while maintaining good ductility.…”

2014) Effects of particle/matrix interface and strengthening mechanisms on the mechanical properties of metal matrix composites, Composite Interfaces, 21:5, 415-429, A randomly distributed multi-particle model considering the effects of particle/matrix interface and strengthening mechanisms introduced by the particles has been constructed. Particle shape, distribution, volume fraction and the particles/matrix interface due to the factors including element diffusion were considered in the model. The effects of strengthening mechanisms, caused by the introduction of particles on the mechanical properties of the composites, including grain refinement strengthening, dislocation strengthening and Orowan strengthening, are incorporated. In the model, the particles are assumed to have spheroidal shape, with uniform distribution of the centre, long axis length and inclination angle. The axis ratio follows a right half-normal distribution. Using Monte Carlo method, the location and shape parameters of the spheroids are randomly selected. The particle volume fraction is calculated using the area ratio of the spheroids. Then, the effects of particle/matrix interface and strengthening mechanism on the distribution of Mises stress and equivalent strain and the flow behaviour for the composites are discussed.
