中文摘要：通过管材对内高压成形过程中产生的起皱、折叠、屈曲和破裂等这几种常见缺陷机理进行深入分析研究，找出了失效原因，提出了较为可行的解决方案，对内高压成形的产品具有实际指导意义。
英文摘要：The failure mechanisms of some common defects, such as wrinkle, fold, bend and crack in tube internal high-pressure forming process were studied to find the reasons of failure. The feasible schemes were put forward, which had practical guiding significance in tube internal high-pressure forming process.
