中文摘要：
介绍了铝型材挤压过程数值模拟的基本理论，包括描述流体运动的方法、材料模型及本构关系、控制微分方程等。分析了有限元法和有限体积法在铝型材挤压过程数值模拟中的应用现状，发现有限体积法由于采用欧拉描述，能避免网格畸变及重划而具有技术优势，并开始受到重视，提出了有限元法及有限体积法在铝型材挤压过程数值模拟中应用的研究重点及发展趋势．
英文摘要：
The basic theory of aluminum extrusion process numerical simulation was introduced, including fluid-flow describing methods, material model and constitutive equations, differential control equations, etc. The application of finite element method and finite volume method in aluminum extrusion process numerical simulation was analyzed. Finite volume method manifests its technical priority and gains attention for avoiding mesh-distortion and regeneration with Eulerian description. The research focal point and developing trend of the FEM and FVM application in aluminum extrusion process numerical simulation were proposed.
