【英文摘要】 By the continuous method,the self-contained displacement shape functions are constructed,and then the formulae of normal stress and shear stress in the core tube subjected to vertical forces are derived. On the basis of this,formulae of the strain energy in each part of the core tube are obtained. Then,the stress differential functions and their boundary conditions are determined by the principle of minimum potential energy. The vertical displacement value of the core tube could be found by solving the differe...
