integration algorithm SUMMARY Real-time hybrid simulation is a viable experiment technique to evaluate the performance of structures equipped with rate-dependent seismic devices when subject to dynamic loading. The integration algorithm used to solve the equations of motion has to be stable and accurate...
Because the size of the time step needs to be extremely small (about 1 μs in typical car-crash simulations), an explicit integration algorithm typically requires numerous time steps. Despite the fact that the calculation within each time step is inexpensive, use of this type of algorithm is ...
