In this paper, the results of numerical studies on the divergence and flutter instability and vibration of a geometrically nonlinear column subjected to generalized load are presented. The system is loaded by axially applied external force P. The direction of action of the force is dependent on follower factor η. The Hamilton principle was used to formulate the boundary problem. Due to the geometric nonlinearity, the solution to the problem was performed by means of the perturbation method. The main purpose of this paper is to investigate the influence of the location of the crack on divergence and flutter loading as well as natural vibration frequency. The presented results of numerical calculations also concern the influence of rotational spring stiffness and follower factor η on the investigated parameters.
