An incremental micromechanical scheme for nonlinear particulate composites. (Q5932315)

The authors study an incremental micromechanical scheme for nonlinear particulate composites. The advantage of this scheme is that it can reflect partly the effects of the third invariant of stress on the overall mechanical behavior of nonlinear composities. The main difficulty here is the determination of effective compliance tensors of the anisotropic multiphase composites. This is completed by the authors by making use of the generalized self-consistent Mori-Tanaka method which was developed by other scientists. A comparison of the present results with existing analytical results demonstrates that the present incremental scheme is quite satisfactory. Based on this incremental scheme, the overall mechanical behavior of a hard-particle reinforced metal matrix composites with progressive particle debonding damage is investigated.
