Abstract

One of the scientific challenges during extreme fluid-structure dynamics is the rigorous description of the loading, its distribution, and the influence of fluid-structure interaction (FSI) effects. Until now, it has been assumed that the loading could be obtained from point-wise measurements on massive, non-deformable structures. We lack the measurement techniques to determine the full-field surface pressures and the FSI effects during large deformations in the structure. In this talk, we will take a walk through the experimental and numerical frameworks developed at SIM Lab, NTNU (https://www.ntnu.edu/kt/simlab) to study FSI effects on plated structures. The talk is mainly oriented towards studies involving blast-like loading conditions using a shock tube facility. Special focus will be placed on some scientific findings on the effect of FSI on the response of blast loaded steel plates. The talk will also include a brief discussion on how micro-architectured materials can be studied in these frameworks. We will close with a short discussion on the next steps towards developing novel methodologies and science-driven tools to quantify the surface pressures acting on plated structures during extreme loading events.
