| Abstract: | The linear and approximate non-linear as well as finite deformation theory of beam, plate and shell are compared. The finite rotation theory is introduced. It is pointed out that by using the finite deformation theory to solve the beam, plate and shell problems, the high efficiency and high precision can be achieved. |

| Keywords: | finite deformation finite rotation work conjugate |
