| 摘 要： | 阐述了铁磁形状记忆合金（Ferromagnetic Shape Memory Alloy,简写为FSMA）本构模型研究的重要性。以时间为顺序,重点介绍了FSMA本构模型研究的发展历程和研究现状。仔细分析了各种FSMA本构模型在理论基础、适用范围、精度以及复杂程度等方面的特点,讨论了各种理论应用于FSMA本构模型的局限性,指出了它们在面向应用时存在的问题。研究表明,由于FSMA兼具磁致形状记忆效应、热弹性形状记忆效应等多种独特性能,使对其本构模型的研究存在一定困难,进一步的研究还有待开展。最后指出,对既能揭示FSMA微观机理又能预测其宏观热磁力学行为的本构模型、描述FSMA所有特性的统一模型、面向应用的FSMA简化本构模型等问题,尚有待深入研究。

| Abstract: | The importance of research on ferromagnetic shape memory alloy（FSMA） constitutive model was described.The development course and research status of FSMA constitutive model was emphatically introduced chronologically.The characteristics of various FSMA constitutive models such as basic theories,application scope,precision and complex degree were anatomized.And the limitations of various theories used in FSMA constitutive model were discussed.Then the problems may happen in actual application were pointed out for further research.Thus,it can be concluded that there were some difficulties in the study on the constitutive model owning to the characteristic that FSMA has so many unique properties such as magnetic shape memory effect,thermoelastic shape memory effect,and so on,so it should be improved in this field.Some problems and challenges such as FSMA constitutive model for both micro and macro scope,FSMA united model for its all properties and FSMA simplified constitutive model oriented to application need to be further studied. |
