Failure
Based on the capabilities of DIGIMAT, the nonlinear multi-scale modeling platform for the simulation of composite materials and structures, micromechanical material models can be calibrated based on strain rate and temperature dependent experimental measurements. These models can be enhanced by the definition of failure indicators introduced on the micro- or the macroscopic level of the composite.
DIGIMAT material models bridge the gap between processing simulation and classical FEA. Based on the prediction of fiber orientations coming from injection molding simulations, the local microstructure in the material can be accounted for in LS-DYNA simulations. For injection molded parts this approach gives much better results when investigating the energy absorption or failure of plastic parts.
This seminar deals in detail with the coupling of DIGIMAT with LS-DYNA for the simulation of impact scenarios of injection molded plastic parts. Participants will get an overview over the multi-scale modeling strategy used. The necessary experimental foundation and the calibration of the DIGIMAT material models will be discussed. This includes a survey of the available failure indicators and their application. The implementation of the material model and the connection to injection simulation results by mapping of the fiber orientations will be covered. The overall focus lies on the workflow of the simulation approach following an applied example.
