This image presents two generations of researchers. It reminds us of the continual evolution of the sciences. </div><div>Behind, the metal frame isolates the suspended test items from ambient vibration. The two large cast iron beds minimize the transmission of ground vibration (car traffic seismic, steps). A beam is suspended by two almost invisible fishing wires from the frame; it is ready for vibration testing. With this setup, it is possible to do fundamental research on the dynamics of built-up structures. Our goal is to understand what is happening inside a connection between two parts of the beam during vibration. </div><div><br></div>
