CALCULATION OF DEFORMATION OF ROD OR TUBING WITH INITIAL BENDING STRESS
Axial force has a great effect on deformation of rod or tubing with initial bending stress. For this reason,this paper analyses the problems of existing calculation method of deformation of red or tubing,presents a new methed to calculate deformation of rod or tubing by taking place of initial bending stress with equivalent lateral concentrated stress on the basis of the law of conservation of energy.
