Modified Specht's plate bending element and its convergence analysis

T. M. Shih and Junbin Gao

Abstract

This paper discusses Specht's plate bending element, shows the relationships between ${\int }_{F_{\rho }}wds$ or ${\int }_{F_{\rho }}\frac{\partial w}{\partial n}ds$ and the nodal parameters (or degrees of freedom), further it sheds lights on the construction methods for that element, and finally it introduces a new plate bending element with good convergent properties (which passes the F-E-M-Test (cf.[11])) is derived.
