摘要
本文以连续多孔体屈服准则与达西定律为理论基础，建立了用于描述金属及颗粒型金属基复合材料一维等温轴对称压缩变形行为的理论模型，并使用有限差分法对模型进行求解，同时对结果进行了细致的分析。
Taking the yield criterion of continuous porous media and Darcy's law as the theoretical basis,an isothermal one dimension model of axisymmetrical compression was proposed,which describes the deformation behavior of metal and particulate reinforced metal matrix composites in the semi solid state Moreover,the model was numerically solved using the finite differential technique and the calculated results were deliberately analyzed
