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).

Note that the entire experimental setup and the computational framework is identical to FSI-PfS-1. Thus in the following these parts are not repeated but links to the corresponding descriptions provided for FSI-PfS-1 are given.
