Mechanical properties and planar anisotropy of TC1 titanium alloy sheet

摘要:

本文首先全面研究了不同厚度TC1钛合金板料在不同方向的机械性能。在此基础上，采用三角函数对不同厚度下的TC1钛合金板料机械性能分布规律进行了描述。此外，重点分析研究了Barlat''89和Yld2000-2d屈服准则中指数M对材料屈服应力和厚向异性指数分布规律描述能力的影响，并比较了上述两种屈服准则对不同厚度TC1钛合金板料的适应性。

Abstract:

This paper investigates the main mechanical properties of TC1 titanium alloy sheets with different thicknesses, and a useful function that can describe the mechanical properties reasonably through extensive practical application will be used. Meanwhile, planar anisotropies of above TC1 titanium alloy sheets were fully studied by Barlat''89 and Yld2000-2d yield functions with an aim of the influence M value on describing ability for distribution characteristics of material yield stress and anisotropy parameter and comparison of their performances on above titanium alloy sheets.
