Analysis Of Nonlinear Dynamic Structures

It is probable that all practical engineering structures are nonlinear to some extent. In this paper work a two degrees of freedom nonlinear system with zero memory was simulated, modeled and analyzed to show their behavior for different conditions. The limit of chaos was also determined. To achieve these results simulation of dynamic systems was used and analyzed using MATLAB. This was done using sweeping sine forces as an input and controlling the amplitude specially when determining the limits of chaos. Using harmonic balance and FRF good results were achieved and verified.
