Metal foam density

Hi,

Is it possible to calculate voids density in Al foam using hyper works. Actually I have the model but. I do not know how to calculate viod/material fraction.

    @Pranav Hari Hi,

    I have the model of Al7075 foam I just need to measure the fraction of void and material, defining a density for the entire volume (it will be obviously lower than the bulk material one, due to the presence of voids). You can find the file in the attachment.

    Unable to find an attachment - read this blog

    Hi Farper

     

    if you just want to know the density difference between two conditions here is a suggestion:

     

    You can create the model without voids and give the material properties of Al7075 (E, u and Rho)  and find out the mass value from Tools > mass calc

    Then you can create the model with voids and give all similar material properties. you can now see the masses will be different. So comparing both these mass values you can arrive at the new density of your model with voids.
