Industries:

Aerospace

Overview:
“Digimat enables the engineers at ISEMP to perform in-depth studies of complex and realistic microstructures. As they continue to invest into the future they now base their simulation approach on the Digimat software, improving their own research method as well as the education of a new generation of simulation engineers."
Challenge:
  • Processing of CFRP results in residual stresses in the material
  • Residual stresses lead to micro-­-damage & failure of CFRP
  • Goal is to simulate residual stresses of a carbon fiber composite material at the micro scale with realistic topology
Solution:
  • Generation of RVE with continuous fibers and layered microstructure
  • Realistic RVE with stochastically distributed fibers
  • CAD geometry of RVE to be used with external solvers
Results Validation:
"DIGIMAT enables us to perform in depth studies of complex and realistic microstructures. As an invest into the future we base our simulation approach on the DIGIMAT software, both for our research and the education of a new generation of simulation engineers who will be experts in the modeling of materials." Prof. Vasily Ploshikhin, Airbus endowed chair for Integrative Simulation and Engineering of Materials and Processes
Benefits:
  • The FE-­Simulation of laminate layers with inhomogeneous properties enables a detailed analysis of stress distribution and possible origins for different types of micro defect formation
  • Highest stresses can be found at the fiber matrix interface
  • Matrix areas between very close fibers are under higher load
  • Fiber matrix interface between differently oriented laminate layers shows higher stresses
