✦ Synopsis

Stability analyses play an important role in structural dynamics. To treat the occurring problems properly, basic knowledge of the stability theory is required. There are so many dierent solution techniques in scienti®c books and journals that there might be doubts whether the proposed algorithms re¯ect the arising task suciently. Therefore, the objective of the present paper is to introduce a uni®ed stability concept based on Lyapunov Exponents. From this, suitable numerical procedures for dierent types of stability problems can be derived directly. The eciency of the proposed algorithms is documented by means of an appropriate example.

The optimal values of these parameters vary during the iterative solution and they are predicted from the Gerschgörin
