Sažetak
When using numerical modeling techniques, the evaluation of stress reduction strategies for complex geometries, e.g. the Francis turbine of the reversible hydropower plant, requires enormous computing capabilities. Such geometries based on the higher order curves and surfaces can only be modeled by CAD program packages. Importing geometries to numerical packages based on FEM or BEM approaches, requires some simplifications described in the presented paper. The stress reduction strategy, applied on ruptured turbine rotor, is modeled by axisymmetric FEM model and obtained results are presented in the paper.
