POLAT, S. Dynamic Analysis of the Structure Using Substructure Decomposition: Diploma Thesis. Ostrava: VŠB –Technical University of Ostrava, Faculty of Mechanical Engineering, Department of Applied Mechanics, 2019, 46p. Thesis head: Podešva,J. The dynamic analysis of the mechanical structures with large number of degrees of freedom (DOF) was in the past the problem of the machine time and disk space. On the today’s hardware it is possible to solve 106 equations without big problem. But if the algorithm requires the iteration approach (non-linearity) or solving the dynamic problem via direct numerical integration this could take long time and large disk space. In this case the domain decomposition could give the advantage. The thesis describes the solution of the dynamic analysis of the structure with using so called “super-elements”.
