Introduction

Review of previous studies

Choice of test case

In the present study a slightly different configuration than in FSI-PfS-1 is considered. Nevertheless, both cases belong to the same series of investigations carried out in order to provide appropriate benchmark test cases for FSI.

Again the structural model consists of a fixed cylinder with a rubber tail (different material than before). Furthermore, in contrast to FSI-PfS-1 a rear mass is attached to the (para-)rubber plate. These modifications lead to stronger (completely two-dimensional) deflections and another swiveling mode of the structure. Again, strong emphasis is put on a precise description of the experimental measurements, a comprehensive discussion of the modeling in the numerical simulation (for the single field solutions as well as for the coupled problem) and the processing of the respective data to guarantee a reliable reproduction of the proposed test case with various suitable methods. A detailed description of the present test case including all details of the experimental investigations is published in Kalmbach and Breuer (2013).
