Card image carbon fiber (Ls-Dyna)

Recommended Posts



I am trying to set up a hypermesh model to export and simulate to Ls-Dyna. The model is a carbon fiber nose cone which I want to make a frontal impact test.

I do not know which card image I have to use for carbon fiber, there are some of them that maybe work:




I believe the best option is the MATL59, but I am not sure. Anyone could help me please?

Thank you

The following lines from the attached documents will favour the usage of M54_55 material card.


The LS-DYNA MAT54 material model is of interest for large full-scale structural damage simulations because it is a relatively simple material model which requires minimal input parameters. Not only does this reduce the computational requirement of a MAT54 simulation, it also reduces the difficulty and amount of material testing necessary for input parameters. Material 54 uses Chang matrix failure criterion (as Material 22), and material 55 uses the Tsay-Wu criterion for matrix failure.
