Material law69

Hello

I am using MAT69 for my model. But I dont understand well about fct_ID_blk Function which scales the bulk coefficient as a function of the relative volume.

In my opinion this function allow to scale up the Bulk modulus as a function of relative volume so I created one curve with X is the relative volume and Y is the scale factor but nothing changed.

Could you please explain me about this function!

Thank you

Hi pohan

 

fct_IDblk is an option that provides additional control for the incompressibility.

Please refer this forum post which discusses about MAT law 69.
