    • Segmentation of pores in carbon fiber reinforced polymers using the U-Net convolutional neural network 

      Autor: Yosifov, Miroslav; Weinberger, Patrick; Plank, Bernhard; Fröhler, Bernhard; Hoeglinger, Markus; Kastner, Johann; Heinzl, Christoph
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      This study demonstrates the utilization of deep learning techniques for binary semantic segmentation of pores in carbon fiber reinforced polymers (CFRP) using X-ray computed tomography (XCT) datasets. The proposed workflow ...

    • Simulation of a multimaterial model for modified auxetic structures 

      Autor: Engel, Alexander; Jung, Anne
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      Auxetic structures, which is a term used to describe materials with a negative Poisson’s ratio, show beneficial properties like a low density, a high energy absorption capacity and an increased indentation resistance. This ...
