THEORY AND APPLICATIONS OF INCOMPATIBLE AND HYBRID ELEMENT METHOD——IN MEMORY OF PROF. WU CHANGCHUN

This memorial paper gives an overview of Prof. Wu Changchun's main contributions to computational mechanics, especially his pioneering work on the incompatible and hybrid element method and its applications. The general formula for the incompatible shape functions and the optimization design method for hybrid stress elements proposed by Prof. Wu are still important means to develop high performance finite elements and are cited by peers constantly.
