【Abstract】 A 3 D FEM stress analysis system of the turbine blade with perfect pre process and post process functions has been developed in this paper, and the 3 D incompatible block element with eight nodes is used in the calculation. This kind of element is more precise than the 3 D compatible block element with eight nodes when the bending load such as steam force exists. This system is convenient, precise and audio visual. Finally, the numerical computation results of a real blade are presented.更多还原
