DAMAGE MICROMECHANICAL ANALYSIS OF METAL MATRIX COMPOSITES

摘要: 通过假定增强颗粒的强度符合Weibul分布,利用细观力学的方法分析了金属基复合材料增强颗粒断裂随外载的演化关系,及颗粒的大小、分散程度对其宏观性能的影响.结果表明,增强颗粒的平均尺寸对复合材料的宏观性能有较大的影响.对一种SiCP铝基复合材料,上述理论分析与文献中的实验结果吻合较好.Abstract: Using the Simple High-order Shear Deformation Laminate Theory and large deformation theory, the geometricnonlinear analysis of rubber rectangular composite laminate plate is presented. Compared with the linear theory, the results, including stress and strain distributions, are more reasonable.
