Title:
Impact of model reduction on frequency responses of linear and geometric nonlinear finite element models 
Chapter contribution:
DFG-PP 1897.01: Calm, smooth and smart - novel approaches for influencing vibrations by means of deliberately introduced dissipation 
Abstract:
Analyzing the behavior of mechanical structures with regard to periodic excitations is an important tool in structural mechanics. Complex structures are typically assembled of multiple components. Thus, the transfer function of an individual component, from one mounting point to another, naturally plays an important role in the overall system behavior. In industrial applications a single component can possess several hundred thousands to millions of degrees of freedom, rendering the calculation...    »
