Impact on a brittle material

[LE Ba Danh]

Hi Damien,
I looked at your numerical test of impact on a brittle material:


1. What is the fracture model of material that you used in GranOO (brittle, no brittle)?
2. if I want to change the bullet by a different form (see figure below). How I can create this bullet in GranOO?


Thank for your help.

Hello Danh,

Yes, this is brittle fracture. If you want to make a bullet instead of a sphere, you just have to build a STL file and convert it to the OFF format. GranOO is able to read OFF files.

You can use meshlab to make this conversion.

I will try to find the source of this simulation and send it to you.

Kind regards, Damien

Thank you so much Damien,
Could you send me the source of impact test when you find it.

Thank you,
Danh

Hope this help, Damien

many thank my friend

Hi my friend,
1. There are errors when I run the calculation:

What is the problem?
2. Why it does not display discrete element of disk in granoo-view? How we can choose this option in GranOO, it's interesting.
 

Thank you Damien,
