    • Advanced mechanical simulation models for automatic panel benders 

      Hammelmüller, Franz; Zehetner, Christian; Pechstein, Astrid S.; Kunze, Wolfgang; Holl, Helmut J.; Irschik, Hans (CIMNE, 2013)
      Conference report
      Open Access
      With automatic panel benders complete products are manufactured from sheet metal. In order to achieve short cycle times with high flexibility, a deep insight into the non-linear bending process is required. For this reason, ...
    • Comparison of coupled euler-lagrange and smoothed particle hydrodynamics in fluid-structure interaction 

      Zehetner, Christian; Schörgenhumer, Markus; Hammelmüller, Franz; Humer, Alexander (CIMNE, 2015)
      Conference report
      Open Access
      In this paper a fluid-structure interaction problem is investigated, in which fluid flow and flexible deformations of structures are coupled. Exemplarily, the collision of a moving deformable water-filled container with ...
    • Increasing numerical efficiency in coupled Eulerian-Lagrangian metal forming simulations 

      Hammelmüller, Franz; Zehetner, Christian (CIMNE, 2015)
      Conference lecture
      Open Access
      The coupled Eulerian-Lagrangian formulation is an efficient tool for modelling and simulation of metal forming processes with large deformation. In many cases, thermo-mechanical coupling has to be considered. Usually the ...
    • Industrial application of advanced adaptive concepts for automatic panel benders 

      Kunze, Wolfgang; Zehetner, Christian; Hammelmüller, Franz; Cojocaru, Eugenia C.; Holl, Helmut J.; Irschik, Hans (CIMNE, 2013)
      Conference report
      Open Access
      Recently, the requirements on sheet metal production processes have increased significantly. Highest precision and flexibility with efficient energy consumption and short cycle times can be achieved by advanced concepts ...
    • Similarity methods in elasto-plastic beam bending 

      Zehetner, Christian; Hammelmüller, Franz; Irschik, Hans; Kunze, Wolfgang (CIMNE, 2015)
      Conference lecture
      Open Access
      In industrial metal forming processes a large number of parameters has to be considered. As is well known, this number can be reduced by a non-dimensional representation. Based on the example of an elasto-plastic cantilever ...
