is influenced not only by the tube materials properties m (including work hardening exponent n, strength coefficient K and anisotropic exponent R, etc), geometrical parameters such as relative bending... Forming characteristics of thin-walled tube bending process with small bending radius LI Heng(李 恒) , YANG He(杨 合), ZHAN Mei(詹 梅), GU Rui-Jie(谷瑞杰) Department of Materials Forming......
of these three types of specimens under the same conditions. It is found that the bending strength of B2-section specimens was increased by 6.47% for pure bending state and 8.12% for non-pure bending state, compared with that of B1-section specimens. Bending strength of B3-section specimens was almost the same with that of B1-section specimens under pure bending, but a little smaller than......
