Abstract
Based on the experiments,the stress-strain state along the tangential direction of outer side of tube bending and the direction of the wall thickness is analyzed and related mean strain calculating formula is also derived.According to that above mentioned,the calculating formula of minimum relative bending radius limited by tube extending rate and extending intensity is deduced.It is pointed out that the authentic mechanical function of tube materials possesses significant influence upon the approximate calculation of the tube bending formation and the minimum relative bending radius.
