| Abstract: |
| Based on the traditional distortion theory which did not take shear deformation into account, the warping displacement function and tangential displacement function under anti-symmetrical load are supposed. Then taking shear deformation into account and with potential principle, the governing differential equation for distortion angle subjected to uniformly distributed distortion load is established. The differential equation is solved and the format of initial parameters is deduced. With a case, the theory proposed in this paper is verified. It is drawn that taking shear deformation into account results in a fairly higher accuracy. |
