| Abstract: | This paper puts forward a boundary solution to thetorsion problem of rods with an arbitrary section.Both the prineipleand the computer program of the method are much simpler than th-ose of the finite element method and the boundary element method.Effects of the method in this paper are satisfactory.The results givenin this paper manifest that the convergence of the method is verygood,and so is the accuracy. |
