【摘要】 近20年来超弹性合金在机械和电子行业得到了广泛应用,但关于其性能的研究工作主要集中在丝材单向加载条件下,而对于复杂加载情况则涉及较少。本文研究了超弹性合金在轴对称加载条件下的行为,并分析了其变形特征和恢复特性。更多还原

【Abstract】 Mechanical properties of NiTi superelastic alloy wire has been widely studied by means of uniaxial tension and compression tests.However,the study of its properties under complex loading condition was rare.In this paper,the axial-symmetrical loading is applied to NiTi superelastic alloy to test its mechanical properties in complex loading condition.The deformation and recovery behaviors are studied simultaneously.更多还原
