-
摘要: 材料的本构关系作为金属成型理论的根本,在加工仿真领域具有重要作用。本文综述了金属切削加工本构关系的研究现状,主要介绍了几种常用本构模型的优缺点,在实际加工过程中的应用以及对其进行的修正工作,同时介绍了本构模型原始参数的获取和修正方法。最后分析了金属切削加工本构模型中存在的一些不足以及未来的研究方向。Abstract: As the basis of metal forming theory, material constitutive model plays an important role in machining simulation. In this paper, the research status of constitutive relation in metal cutting is reviewed. It mainly introduces the advantages and disadvantages of several typical constitutive models, their applications in the actual machining process and their correction, also the acquisition and correction methods of original parameters of the constitutive model. Finally, some deficiencies in the constitutive model of metal cutting and the future research direction are analyzed.
