Abstract: Conventional approach to solutions of structural mechanics problems depends on analytical solutions and perturbation analysis. Main feature of structural mechanics problems and computational methods to solve them is that the problem size is extremely large in comparison with the model orders of control systems. On the other hand, structural mechanics problems can be formulated as an multi-input-multi-output system and input-output analyses techniques of system theory can be applied. Such an approach gives more insight into the associated problems and enables one to develop solutions by the use of system theory results.
In this talk, semi-discrete thermal and structural mechanics problems will be examined. Conventional time-integrators will be elaborated and results on the stability and convergence of them will be revisited. Following, input-output analysis of the equations will be presented. Digital control and frequency domain analysis methods will be employed to study these methods. Solutions of sample problems will be given. Benefits of input-output point of view will be shown.
