Summary

This paper presents a new finite element model for the dynamic analysis of thick rotating blades with flexible roots. The new model is based on the fast convergent element developed by Abbas and Thomas which can satisfy all the geometric and natural boundary conditions of a thick non-rotating blade. It is the only element developed so far which can distinguish between roots of blades that are rigidly clamped and are elastically supported.
