Micromechanics Interface (MMI)

Why Micromechanics Interface Module?

Micromechanics Interface (MMI) is a module which allows users to output more material properties for nonlinear multi-scale material modeling with integration of Digimat and Converse before FEA software. After finishing molding process simulation with composite materials in Moldex3D, users are able to use MMI model to solve complex nonlinear multi-scale finite element structural analysis more accurate and efficiently. In addition, the unique material properties can be considered into the multi-scale model are

  • Anisotropic, corresponding to the microstructure morphology
  • Heterogeneous, corresponding to the microstructure morphology
  • Nonlinear, elasto-plastic
  • Fatigue
  • Failure
  • Strain-Rate dependent, visco-elastic

 

Challenges

  • How to obtain the various material property that induced from molding process such as weld line, fiber orientation, residual stress and etc
  • How to transfer the material properties variation of molded part for FEA applications
  • Evaluation to advanced molding process, such as MuCell®, and how does it effects the part structural performance

What Can Moldex3D Do?

  • Interfacing with direct selections of output items for Digimat and Converse analysis before FEA software
  • Support to continue with structure analysis in ANSYS, ABAQUS, MSC-Nastran, Marc, LS-DYNA and Radioss
  • To cover complete process-induced variation during the molding processes, the output items include:
    • Fiber orientation
    • Weld line region data
    • Residual stress
    • Digimat-MAP allows to map the residual stress data and account it as input of mechanical simulations
    • Temperature distribution at EOP and EOC
    • Include part and part insert object
    • Temperature before and after the cooling step could be used to perform warpage analysis by Digimat
