圆管的弹塑性变形分析及有限元模拟

摘要

The mechanical characteristics of the external pressure applied to the thick-walled tube was analyzed ,the elastic and plastic deformation of the thick-walled tube was simulated by ANSYS finite element software ,and the deformation law ,the stress and strain distribution of tube were obtained .This study may provide effective help for the research and use of hydraulic flexible forming .%通过分析厚壁圆管施加外压的受力特点，使用ANSYS有限元软件对厚壁圆管弹塑性变形进行模拟，分析圆管的变形规律和应力、应变分布状况，对液压柔性成形的科研和运用提供有效的帮助。
