Abstract

The paper deals with a shaft subjected to an axial pressure with force P and relatively high moment of rotation M. In order to determne the lines of deflection we propose various approaches. The assessment of critical values of P and M is also discussed when loss of stability is available. Thus two fourth-order eigenvalue problems are considered and their mixed variational models are proposed. Finally, some numerical experimental results are presented.
