Honeycomb card

Hi guys,

Sorry if I ask another question. I don't understand some parameters in the card M28_HONEYCOMB. Is the strain the absissa of this curve? The last point of the curve is the yield or the rupture? Or it is only a function stress-strain and the epsilon values are our input to describe the rupture of the elements? 

Fscale is an addend to the function? Because I saw in the help that its dimension is Pascal so I thought that it isn't a factor.

I'm asking all this questions because I'm thinking how I can simulate a buckling of the cell changing the yield function if my suppositions are right.

Thanks a lot for the attention

Best regards

    Hi,

     

    the strain is abscissa, refering to figure from Help:

    E modulus is used for loading/unloading until intersections with the curve.

    EPSMAX parameter is epsilon value for the rupture of elements.

    FSCALE are usually scale factors for curves.

     

    So I suppose your suppositions are correct.

    In help, the units shown is an example.
