| 英文摘要 | This paper presents a novel failure evaluation method for fracture instability analysis of ring-stiffened titanium alloy cylinders under hydrostatic pressure. The quantification of fracture instability behavior for a titanium alloy cylinder remains unclear. In this work, we propose a post-buckling mode analysis for fracture instability, considering the relationship between plastic strain and structural deformation. Further, a novel fracture failure criterion involving material properties and structural parameters is established, bringing the proposal of a structural failure range evaluation method for titanium alloy cylinders. By incorporating the strain rate effect into the constitutive model of the two-phase alpha+beta\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\alpha +\beta $$\end{document} titanium alloy Ti-6Al-4 V, we developed a dynamic finite element model for studying the fracture instability of the titanium alloy cylinder. The theoretical results and finite element simulation results are finally verified by the collapse experiment of a titanium alloy cylinder. The findings can provide a fundamental basis for designing and service safety evaluation of titanium alloy cylinders. |
