Industries:

Automotive

Overview:
Digimat provides L&L Products with state of the art simulation methods which aid engineers in product development. The key advantage provided by Digimat coupled to Radioss and other CAE software is a drastic predictability improvement for glass filled polyamide materials. With an improved predictability, optimal and robust lightweight design is possible in the future.
Challenge:
  • To move towards greener technology by replacing classical metal design by composite structures
  • To use the outstanding performance of composite materials whilst tackling all additional difficulties arising from the injection molding process
  • High quality prediction of impact on a short fiber reinforced stiffener beam
Solution:
  • Strain rate dependent micromechanical material model for AKULON K224 HG7 supplied by DSM
  • Mapping of MOLDFLOW fiber orientations onto the structural mesh
  • Solution of a nonlinear multi-scale analysis with DIGIMAT coupled to RADIOSS
Results Validation:
"The key advantage provided by DIGIMAT coupled to Radioss and other CAE software is a drastic predictivity improvement for glass filled polyamide materials. With an improved predictivity, optimal and robust lightweight design is possible in the future." F. Braymand, Simulation Manager at L&L Products
Benefits:
  • Excellent correlation on the force-­-displacement curve with experiment
  • Excellent correlation on the failure location compared to experiment
  • Drastic improvement of predictivity enables robust and lightweight design focusing on cost efficiency based on advanced DIGIMAT CAE technology
