摘要
比较了有限元法与无网格法在金属成形应用中的优缺点,分析描述了无网格法在金属弹塑性变形、金属体积成形、板料成形等金属成形加工方面的应用现状,并阐述了无网格法的不足、亟待继续深入解决的问题以及未来的展望。
The advantages and disadvantages of the finite element method and meshless methods applied in metal forming are compared. The application status of the meshless methods in metal elastic-plastic deformation, metal bulk forming and sheet-metal forming is analyzed and depicted. The disadvantages, some research topies for solutions and prospect of the meshless methods are described.
