Abstract

A method of simulation is developed for studying the dynamics of the structures with discontinuities using Matlab–Simulink. The concept of dynamic compliance is used for modeling the continuous elements of the structure and the local discontinuity is modeled as nonlinear feedback. As an example, a one-dimensional model of cracked bar under harmonic loading is considered for the simulation purpose.
