Wrinkling behavior of the ultra-thin components with variable cross-sectional perimeter during bending process with local support

ZHUANG Yongpeng, HAN Cong

Abstract: The wrinkling behavior of the ultra-thin components during the tube bending process was investigated by finite element analysis and confirmed by experiment and the causes of various typical defects were explored. The tube was bent through three local support methods: without support, hard support, soft support. The results indicate that severe wrinkling behavior of pipes occur during bending process. However, in the case of soft support, the wrinkling behavior of the pipe is suppressed and flattened during the subsequent bulging process.
