本文研究了S与L、S等人在圆管翻转或内翻过程中所遇到的变形过程。引起反转所需的载荷由p L a S t i c在单轴p L a S t i c应变过程中吸收的能量的基本表达式解析地推导出来。将分析结果与S、L、S同时进行的实验结果进行了比较，并与文献报道的结果进行了比较。反转载荷的实验值与分析预测值在10%~30%的范围内吻合。
This study i s concerned with t h e p l a s t i c deformation process encountered i n t h e inversion or turning inside out of a circular tube. The load required t o cause inversion i s derived analytically from elementary expressions f o r p l a s t i c energy absorbed during uniaxial p l a s t i c straining. Analytical results a r e compared w i t h the r e s u l t s of experiments conducted concurrently, and with previously reported results. Experimental values of inversion load agreed with analytical predictions within 10 t o 30 percent.
