采用理论分析、有限元模拟和拉伸试验相结合的方法，研究了纯钛（TA 2）管材的各向异性拉伸力学性能。通过对TA 2管材环向拉伸的应力分析，建立了环向拉伸试样切向力的计算公式，分析了环向拉伸试样切向力与摩擦力、环向试样位置之间的关系。对TA 2环件周向拉伸过程进行了有限元模拟分析，验证了理论分析推导的切向力方程。分析了标距和摩擦力对颈缩和拉伸载荷的影响，选择了环箍拉伸试验的最佳标距。最后，进行了轴向和周向拉伸数字图像相关实验，验证了理论和有限元模拟结果。通过有限元逆分析和摩擦实验，确定了TA 2管与D型块（使用Teflon润滑剂）之间的摩擦系数，得到了TA 2管的真实应力-应变曲线。结果表明，TA 2钢管的轴向和周向力学行为存在显著差异，且各向异性明显。
The anisotropic tensile mechanical properties of pure titanium (TA2) tubes were studied by means of theoretical analysis, finite element simulation and tensile tests. Based on the stress analysis of circumferential tensile of TA2 tube, an equation for calculating the tangential force of circumferential tensile specimen was established, and the relationship among tangential force, friction and position of ring specimen was analyzed. The finite element simulation analysis of circumferential tensile process of TA2 ring specimen was carried out, which verified the tangential force equation derived from theoretical analysis. The effect of gauge length and friction on necking and tensile load was analyzed, and the optimal gauge length was selected for the ring hoop tensile test. Finally, the axial and circumferential tensile digital image correlation experiments were carried out to verify the theoretical and finite element simulation results. The friction coefficient between TA2 tube and D-blocks (using Teflon lubricant) was determined by the inverse finite element method and the friction experiment, and the true stress–strain curve of TA2 tube was obtained. The results show that the axial and circumferential mechanical behaviors of TA2 tubes are significantly different and anisotropic.
