| Abstract: |
| he similarity theory between plane elasticity and plate bending is established and applied to the use of finite elements of plane elasticity in plate bending. Therefore the theories such as patch test and FE convergence etc. can be moved to plate bending, thus both sides will be on the same theoretical level. Afterwards these complementary energy method based plate bending elements are derived into the track of displacement method, the composition of the displacement vector is found and its consistency is proved, which enables installing these elements into the general finite element program system. |
