Abstract

In the following article impact experiments from experimental and numerical point of view will be described. In order to keep the number of parameters to be varied manageable, the focus was firstly on similar plain concrete plates. The experiments were carried out with the aim to collect reference values and to simulate these experiments as basis for further investigations. The only parameter that has been changed was the impact velocity. The experimental part of the publication deals with manufacturing of the specimens, the experimental setup, the execution of the experiments, the measured values, and a brief evaluation of the results. The numerical part of the publication deals with the computation of experimental results using the simulation program LS-Dyna. In this context, it will be explained how the model was created and which boundary conditions and material models were used. Furthermore, the calibration of the materiel law is described. Subsequently, a comparison between the experimental and simulated results is carried out. The focus of the further investigations will be the consideration of concrete layers reinforced with textiles under impact load. The work presented here deals with the matrix material of the textile reinforced concrete and thus laid the foundation for these investigations.
