The aim of this paper is to study the evolution of nonlinear dynamics of structures with a propagating crack. A method of simulation used for analysis of dynamics of the cracked structure is based on a combination of an analytical technique and Matlab-Simulink-based simulations. As an example, a model of a cracked bar subjected to longitudinal excitation is used to analyse its nonlinear response as a way to monitor the structural health as crack propagates.
