Modified Specht's plate bending element and its convergence analysis (Q1344411)

This paper discusses Specht's plate bending element, shows the relationships between \(\int_{F_ \rho} w ds\) or \(\int_{F_ \rho} {{\partial w} \over {\partial n}} ds\) 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 is derived.
