几何特征对SiC颗粒增强Al基复合材料力学行为的影响 陈志谦1,强华1,徐尊平1,程南璞1 (1.西南大学,重庆,400715) 摘要:利用有限元方法建立三维模型分析SiC颗粒在不同形状,不同体积分数和不同尺寸时对Al基复合材料力学行为的影响,并进行拉伸试验研究.结果表明,颗粒形状比颗粒尺寸和颗粒体积分数对材料的应力,应变分布及材料韧性的影响大.颗粒尖角附近有严重的应力集中现象,在外力方向上颗粒端部附近的基体上的应变也有集中现象.随颗粒角度的减小,颗粒的应力很快增大而韧性减小,材料的弹性模量有增大的趋势.随颗粒体积分数的增大,颗粒的应力有减小趋势,材料的弹性模量呈增大趋势.颗粒尺寸较小时(平均尺寸为5 μm),颗粒尺寸对材料的应力及应变的影响小. 关键词:SiC颗粒; Al基复合材料; 三维模型; 力学性能; SiC particle; Al aluminum-matrix......
