Abstract

The discrete scheme called discrete operator difference for differential equations was given.Several difference elements for plate bending problems and plane problems were given.By investigating these elements,the ability of the discrete forms expressing to the element functions was talked about.In discrete operator difference method,the displacements of the elements can be reproduced exactly in the discrete forms whether the displacements are conforming or not.According to this point,discrete operator difference method is a method with good performance.
- discrete operator difference method,
- element function,
- reproduce exactly
