SiCp/Al复合材料热轧过程的有限元模拟*
DOI: 10.11900/0412.1961.2015.00210, PP. 889-896

Abstract:
运用热-力耦合有限元法对SiCp/2009Al复合材料进行了热轧模拟,研究了复杂应力状态下的轧制成型过程、温度场、变形场及应力场分布,得到了轧制过程中表面和中心区域的温度、应力、应变以及应变率的变化曲线,从而可以更好地理解复合材料的热轧机理.模拟结果表明在轧制入口处,最大主应力由压应力向拉应力转变,与出口处变化规律相反.在轧制稳定阶段,变形区的最大主应力则以压应力为主;轧板表面的热传递温降效应远大于摩擦温升效应,而轧板中心温度主要由塑性变形温升效应控制;此外,在轧制入口和出口处,应变率对流动应力的贡献起主导作用;在轧板变形区,轧板表面的流变应力主要由应变和温度决定,但表面黏着区是由应变率控制;轧板中心的流动应力在变形区主要受温度影响.
