| Abstract: | This paper deals with finite element method in power generating machines, and establishes the incremental constitutive equation of three-dimensional elestic-plastic problems. Incremental equation of axisymmetric problem, plane strain problem and plane stress problem are readily derived thereby. By calcalating some examples and comparing this method with the analysis method and the practical, desived results have be achieved. It has found its application in engineering design. |
