Time Integration Techniques to Investigate the Long-Term Behaviour of Dissipative Structural Systems
- 1.2k Downloads
The dynamics of a beam subjected to quasi-periodic excitation is simulated with a finite element model and an energy-conserving based time integration scheme. The numerical methods are capable of reproducing the dynamics of the system if a fixed time step size is applied, whereas the application of adaptive time step seems more problematic.
