Abstract


Metal base composite material has been under the material world and force the attention of academic researchers. Enhance particle effects including enhancement of particle volume fraction, particle shape and particle size. This paper makes a study of a particular enhanced particle particle form - the cylindrical silicon carbide reinforcing particles, aluminum as composite matrix. Of interface between reinforcing particles and matrix using cohesive force model to describe. Using the finite element software ABAQUS to simulate the material, and the load for single axis tensile load. In the same silicon carbide volume fraction, the study of the different dimensions of reinforcing particles than the composite stress-strain relationship. And based on the introduction of the mechanism of plastic strain gradient theory and based on the mechanism of plastic strain gradient expansion theory as the aluminum substrate material constitutive, and with classic elastic-plastic constitutive of aluminum substrate material for comparison, analysis on the whole, the mechanical properties of composite the influence of.
