Abstract
A new stress analysis program SAPRUN-2 is developed to enable analysis of the elastoplastic behavior of centrifugal compressor impellers. In this program three-dimensional curved elements are used and structural periodicity is duly considered. The stiffness matrix is stored in a one-dimensional array. This program has the practical usability from the viewpoints of solution accuracy and computation time, and gives the prediction of the critical angular velocity at the plastic collapse. The numerical results are compared with the experiment and discussed.
