| Abstract: | An approximate stress analysis of a composite material, power law creep material (matrix) reinforced by an elastic short fibre is performed by modifying the Cox model, elastic monofibre in a unit cell of an elastic matrix. The numerical calculation is performed by using aluminium (6061)-SiC (whisker aspect ratio of 10). The result obtained by using the analysis is compared with that obtained by experiments performed by a previous investigator. The result shows that composite stress obtained by the analysis is compatible with that obtained by the experiment in order of magnitude, while stress exponent obtained by the experiment is much higher than that obtained by the analysis. A correction factor relating analytical to experimental results is found and the physical meaning of the factor associated with the actual deformation process is discussed. In addition to this analysis, a rigid fibre in power law creep material (matrix) is analysed. The fibre stress distribution obtained by the analysis is compatible with that obtained by the previous investigator. |
