Abstract: The stress distribution and displacement of the boiler are investigated by CAE software. The geometrical model and the finite element analysis model are established by MSC/PATRAN, and these models are calculated and analyzed by MSC/NASTRAN. At the same time, the classical strength theory of material mechanics is applied to their calculation and strength check. It is shown that the numerical and theoretical methods have the same results.
