A New Compatible Thin Plate Rectangle Element

摘要

By theoretical analysis and iterative trialling, based on routine isoparametric coordinate transformation method, a new compatible rectangle thin plate element is developed in the paper. At the same time, compatibility and completeness of the element are proved theoretically. Numerical analysis results show that the compatible element is higher accuracy and better convergence than the incompatible element; as well as it is a thin plate element of fine performance.
