Abstract
The present paper provides an overview of the structural design of modern steam turbine blades at Siemens power
generation using the finite element code ADINAe. The different types of blades are described in detail regarding their
geometry and loading. The modular building block approach of modelling is shown to be of essential importance. For
the different analyses a fatigue post-processor has been implemented as well as an optimization tool. Both of these in-
house codes will be briefly presented.
